Scientists try to assess Monarch butterfly mortality after Mexican freeze

Scientists have been scrambling  to assess the mortality of the roosting Monarch butterfly population in Michoacán, Mexico, following a freak March 11 winter snowstorm that dropped temperatures to sub freezing and included wind gusts up to 50 miles per hour in the butterflies’ ancestral roosting sites.  For now, the estimates of how much of the migrating Monarch butterfly population perished are at best an educated guess.

“I have no new information. We are ‘in limbo,’” said Dr. Chip Taylor, founder of Monarch Watch, the citizen science organization based at the University of Kansas that tags the butterflies each fall to track their migration.

Dr. Lincoln Brower has been working long distance from his home in Sweet Briar, Virginia, with a team of scientists on the ground in the 10,000-foot-tall plus mountains northwest of Mexico City where the butterflies roost each fall.  They’ve been gathering data, reviewing climatology information, making observations, and reviewing photos and historical accounts of a previous freeze in 2002.

“It’s been difficult and there are conflicting reports as you know,” said Dr. Brower via email, referring to Mexican tourism officials downplaying the severity of the situation. Soon after news of the storm broke, Mexican officials claimed that only 3% of the butterflies had been affected–about 1.5 million of the estimated 200 million roosting.

“The climate data we have suggest about 50% mortality in Chincua but observations suggest that Rosario was hit harder,” said Brower, referring to the El Rosario sanctuary, the preserve most often visited by tourists. The 50% number would mean 100 million butterflies took the hit–which still leaves us up over last year, just a disappointing and devastating turn of events, if true.

Dr. Cuatémoc Sáenz Romero, a forester who studies the Oyamel forest and is promoting an initiative to move it higher in elevation to save it from climate change, thus guaranteeing the Monarchs a future winter roost, said he visited the sanctuaries two weeks after the storm. “Except for some trees fallen, I did not see dramatic damages,” he said.

Many of us are wondering how many of the butterflies had already left the colony when the storm hit on March 11.  Typically the first and second week in March are when the Monarchs bust off the Oyamel trees in response to warmer temperatures and begin their journey north.  We start to see them moving into South Texas as they search for milkweed on which to lay the first generation of eggs in the multi-generation migration. Some Monarchs have definitely made it to San Antonio and South Texas as we are witnessing and hearing about first-of-season sightings and finding eggs on local milkweeds.

The question of how many Monarchs departed before the storm hit may be rhetorical, according to one scientist.

“Perhaps that doesn’t even matter given how widespread this storm was,” said Monarch and migration scholar Dr. Tyler Flockhart of the University of Guelph in Ontario.  Flockhart said that according to weather data, the winds were so strong that temperatures inside and outside the forest were pretty much the same, suggesting the “butterflies would have been exposed to very cold temperatures.”

Scientists consider the forest canopy as an insulation blanket.  As climate change and illegal logging conspire to undermine the forest in the roosting preserves, the unique ecosystem of moisture, temperature and protection from the elements becomes threatened.   Several scientists expressed more concern about the huge trees that had been taken by the storm than the mortality of the butterflies, since it will be extremely challenging to recreate the forest canopy in the short-term.

Meanwhile, a study conducted by the Monarch Conservation Science Partnership and released in the journal Scientific Reports March 21 found that the Monarch migration has an 11 to 57 percent chance of facing “quasi-extinction” in the next 20 years.

Dr. John Pleasants, an Iowa State University researcher who participated in the study, defined quasi-extinction to mean that not enough individual Monarch butterflies would exist to continue their migratory patterns.  The migration would collapse and the population would likely not recover.  That doesn’t mean there will no longer be Monarch butterflies;  it does suggest the phenomenon of the unique Monarch butterfly migration would cease to exist if the population falls to even more perilous levels.

We should have more definitive information in the next few weeks as the scientists review the collected data.  Stay tuned and keep those fingers crossed.

At least 1.5 million Monarch butterflies perish in deadly ice storm in Michoacán

At least 1.5 million Monarch butterflies were hit with a deadly freeze this weekend as an unusual ice and wind storm moved through the mountains of Michoacán where the butterflies roost for the winter.   The storm hit just as the spring migration was beginning.   Luckily, many butterflies exited the mountains before the freeze arrived.

Exactly how many butterflies perished in the freeze remains uncertain. An Associated Press report sounded upbeat, with Mexican authorities stating that “Monarch butterflies that winter in the mountains west of Mexico City survived the severe cold snap that hit the area this week.”

But the Mexican news agency El Universal on Saturday quoted Homero Gómez González, president of the administrative council that oversees the El Rosario butterfly sanctuary, as saying that 1.5 Monarch butterflies froze to death–about 3% of the estimated 50 million roosting.

According to Gomez Gonazaléz, the recent freeze registered temperatures of -12 degrees Celsius (about 10 Fahrenheit). Other reports had winds raging up to 50 miles per hour, leaving 13 inches of snow on the ground in some areas and taking out dozens of trees.  Those living in the area were without electricity for days and hundreds of lamb and sheep were lost.

“Historic snowfall at the El Rosario sanctuary,” read the headline of the el Rosario Facebook page on Thursday, March 10. “The Monarch butterfly suffers wind, snow, rain and sleet.” The post was accompanied by photos showing several inches of snow on the ground.

The news whipsawed those who follow Monarch butterfly news.  Monarch fans had been celebrating the much-anticipated announcement in February that the population of the migrating orange-and-black insects had tripled since last year.  Reports of the devastating freeze underscored the brutal reminder that Mother Nature is in charge.

Dr. Chip Taylor, founder of citizen science group Monarch Watch, which tags the butterflies during their fall migration, weighed in from Kansas.

“Information is still sketchy about the degree of butterfly mortality,” Dr. Taylor told the  DPLEX list, an email listserv of about 800 butterfly aficionados.

Dozens of trees were lost in the storm.

“Most claims, observations and images suggest that mortality is low to moderate,” said Dr. Taylor.  “There is no evidence to date to indicate levels of catastrophic mortality (70-80%) that followed the winter storms of 2002 and 2004.” he said, adding that it will take at least a week to get more accurate information on the number of butterflies lost.

Taylor also reminded readers that “a significant portion of the population had already left” the roosting sites prior to the storm.

Dr. Lincoln Brower, who has studied Monarchs his entire life and is one of a group who submitted a petition to have the butterflies listed as “threatened” under the Endangered Species Act, seemed less optimistic.

“The current statements that the Monarchs have survived the storm are premature,” wrote Dr. Brower via email in response to the Associated Press story.  “I fear that optimistic assumptions are driving the news reports.”

Like Dr. Taylor, Brower cautioned that time will tell the accurate mortality counts.

“Based on our study of the 2002 storm, the butterflies that are killed or irreversibly damaged keep falling out of their clusters for days after the freezing event. Mortality counts need to be made at least a week after the storm.”

San Antonio Zoo to stage three-day Monarch Fest March 4-6

Area butterfly buffs will have a unique opportunity to see exotic butterflies up close and personal while learning about the Monarch butterfly migration at the San Antonio Zoo’s

Laurie Brown Paper Kite

first Monarch Fest March 4 – 6. The inaugural event celebrates San Antonio’s recent national status as the first and only Monarch Champion City, so designated by the National Wildlife Federation’s Mayor’s Monarch Pledge program.

monarchchamplogoLaurie Brown, Zoo volunteer services manager, along with Zoo staff and volunteers, have been preparing for the event for months.   On the agenda for the 72-hour celebration: a native plant sale and seed giveaway, kid-friendly crafts and educational activities, and booths/displays by more than a dozen local pollinator advocacy organizations.  The event is free with zoo admission.  MonarchFestLogo400x287-021616021503

But for an extra $1.50, visitors can also stroll through the Zoo’s butterfly house, an experience well worth the cost. Proceeds go 100% to conservation and education efforts, says Brown.

Inside the flight house, hundreds of exotic flyers like the Malabar Tree nymph,  Idea malabaricaalso known as the Paper Kite,  will be on display in a natural, garden like setting. The wings of this gorgeous black-and-white butterfly, native to India and Southeast Asia, resemble rice paper with a Monarch-like painted glass pattern.

Interestingly, the Paper Kite’s host plant, Apocynaceae, belongs to the same plant family as the Monarch butterfly’s host plant–Asclepias (milkweeds).  Both are members of the dogbane family.  Is it a coincidence that the lovely wing pattern on these two butterflies from opposite sides of the world are similar?

Not really, says Brown.  The Paper Kite and Monarch are distant relatives.

Also scheduled for appearances in the flight house:  the Common banded Peacock,   Papilio crino, sometimes called a Buddhist Heart, sports fluorescent wings can suggest blue or green, depending on the angle from which it is viewed.

Brown promises a couple dozen other exotics, a mix of local butterflies and a handful of amazing Atlas Moths, Atacus atlas, one of the most dramatic looking Lepidoptera.   If you’ve never seen one of these impressive moths up close, you’re in for a treat.

These Saturnid moths rank as one of the 10 largest insects in the world and hail from Southeast Asia.  Their wingspans can reach 12 inches and in Taiwan, empty Atlas moth cocoons, spun from sturdy Fagara silk, are used as purses.

“Some vacated cocoons don’t need to be deconstructed—they can be used ‘as found’ as small pocket-change purses by simply installing a zipper,” according to the educational magazine Mental Floss.

Hmm.  New handbag trend?

Advance tickets are available online or you can buy them upon arrival.   Hope to see you there!

Commercial butterfly breeders: industry has vested interest in raising OE-free butterflies

NOTE:  The following guest post by Dr. Barbara Dorf* arrived as a lengthy comment here at the Texas Butterfly Ranch last week.  I invited Dorf to expand her comment to a full-blown post because I think the perspective of professional breeders is important to various issues discussed here.

–Monika Maeckle

As a board member of the Association for Butterflies, an organization for about 80 professional and hobbyist butterfly breeders and a co-owner of Big Tree Butterflies  commercial butterfly breeding farm,  I am writing today to clarify our position in relation to the proposed petition to the U.S Fish and Wildlife Service (USFWS) to list the Monarch butterfly as threatened or endangered under the Endangered Species Act (ESA).

As stated in a recent post on this website, Lawsuit seeks ESA monarch butterfly listing, turns up heat on commercial breeders, the petitioners believe that commercial breeders release diseased butterflies into the wild population, potentially damaging it.  Such comments oversimplify the butterfly industry and misrepresent the efforts of many breeders who are very diligent and dedicated to raising healthy butterflies.

Butterfly disease is a concern for all ethical butterfly breeders and part of the larger issue of raising healthy butterflies in captivity. Our concern is at several levels.

We want to raise healthy butterflies and provide customers with the best value for their money. In addition, butterflies are living creatures and proper animal care practices need to be observed. Failure to adopt clean rearing procedures is costly and ultimately self-destructive. That said, there are areas of concern.

Ophyryocystis elecktroscirrha, or OE, has been studied extensively and is of particular concern because it can significantly impact Monarch populations. It is the most commonly mentioned disease problem in both the butterfly industry and popular press. OE occurs in nature, primarily infecting Monarchs and related butterflies. It is found in Monarch butterfly populations throughout the world, including North and South America, the Caribbean, Hawaii, and Australia.

OE can be transmitted in two ways. In nature and during captive breeding, spores are transmitted from egg-laying females to their offspring when dormant spores on the female’s body scales are scattered on eggs or as they are passed onto milkweed leaves that are the Monarch’s only host plant. Newly emerged caterpillars consume spores when they eat their eggshell or when feeding on milkweed leaves. Spores can also be spread between adults through body contact, more likely to occur during captive breeding when adults are kept in higher concentrations than in the wild.

Once eaten, the spores have a rather complicated life cycle, with the end result being many more spores, which are often visible inside the chrysalis. When the butterfly emerges spores are located mostly on the abdomen.

OE can be debilitating, often killing or deforming caterpillars, chrysalises and adults. Infected adults have been shown to be smaller, have shorter lives, and mate and migrate less successfully. However, those that do mate can continue to lay eggs, passing on the OE spores to the next generation, both in nature and in captivity.

If not controlled, all butterflies within a captive breeding colony will become infected with OE in very few generations, resulting in poor quality butterflies unable to successfully breed or migrate when released. This is a butterfly breeder’s worst nightmare.

Thus, the butterfly industry has a vested interest in producing OE-free butterflies and educating all breeders on how to produce healthy butterflies. The problem is not that all butterfly breeders raise and sell OE-contaminated Monarch butterflies. Rather, the problem is that customers cannot tell if the butterfly breeder they are purchasing from raises OE-free butterflies.

The AFB has been implementing programs over the last 10 years and has been anything but lethargic concerning OE in commercially raised butterflies.

Here is what the AFB is doing to address the problem:

1. Educational programs

The AFB offers educational programs developed by butterfly professionals and academic researchers available to anyone who wants to learn more about butterfly disease prevention.

Our annual “Disease Prevention in Lepidoptera” course (offered for the last 10 years!) is free to all members and has been taken by hundreds of professional breeders, hobbyists, enthusiasts and educators, and offers a Disease Seal and certification for participants who successfully complete weekly testing and a final exam.

2. Disease screening co-op

In addition to education, the AFB also offers its members a 3rd-party Disease Screening Co-op in conjunction with the Mississippi State Pathology Department.  Caterpillars are screened by pathologists for viruses, bacteria and parasites, helping breeders to detect issues in breeding butterflies before disease can cause serious issues.

3. OE Clean Screen Program

The AFB has initiated the OE Clean Screen Program, a butterfly industry first. This is a 3rd-party OE testing program in which professional breeders voluntarily submit Monarch chrysalises to an independent University laboratory for OE testing when the adult butterfly emerges. Submitting fresh chrysalises eliminates any possibility of “selection” for OE-free AFBlogo

butterflies. Acceptable OE levels reflect natural background levels, with 20% of all butterflies tested having either no OE or showing light contamination (less than 100 spores). The program was set up with comments and advice from Dr. Sonia Altizer, a leading Monarch butterfly researcher and world-expert on OE.

Testing is voluntary and anonymous. Breeders will receive a Clean Screen rating and be highlighted on the AFB website as part of a Preferred Listing. The rating indicates that the breeder has met standards for OE prevention that have been approved by academic researchers. No program with this level of rigor and independent evaluation has ever been attempted. This is a serious program to address a legitimate concern. It is open to all butterfly farmers, even if they do not belong to the AFB.

The purpose of this testing program is not to penalize breeders who may have OE-positive butterflies, but to get a better picture of the butterfly industry, offer support and education, troubleshoot, identify, and correct possible rearing problems, and to encourage all butterfly breeders to do a better job of keeping a clean operation. The result will be that customers will be able to compare butterfly breeders based on this independent standard. The marketplace will determine the rest. Independent, 3rd-party certification allows customers to know that the breeder was producing Clean Screen stock at the time and that they are taking an active interest in producing healthy butterflies. Thus, it is in the butterfly breeder’s best interest, once they have Clean Screen stock, to maintain them.

There are unscrupulous butterfly breeders out there who do not practice clean breeding techniques and give the entire butterfly industry an unfavorable image. Because these unscrupulous breeders exist, buying butterflies from breeders engaged in independent 3rd-party testing allows customers to know that they are buying from a butterfly breeder who is seriously working to produce healthy butterflies.

In closing, butterfly disease is a concern for all ethical butterfly breeders and the AFB is working hard to provide the best possible support to butterfly breeders for rearing healthy butterflies.

Lawsuit seeks ESA Monarch butterfly listing, turns up heat on commercial breeders

The battle to list the Monarch butterfly as “threatened” under the federal Endangered Species Act inched forward last week, as the Center for Biological Diversity and Center for Food Safety announced they will file suit against the US Fish and Wildlife Service (USFWS) for failing to meet a December 26 deadline.

The intent to file suit was announced in a January 5 press release and will be acted upon in 60 days if no ruling is made.

Those specializing in endangered species issues said such lawsuits are not unusual in the often convoluted listing process. After providing an update to the Texas State Comptroller’s Monarch Butterfly Task Force Working Group in Austin last moth, Katie Latta, USFWS Monarch Outreach Specialist, said such lawsuits at times delay the process and other times speed things up.

David Braun, Principal of Braun & Gresham, a Dripping Springs, Texas-based law firm that works with private landowners and communities on endangered species issues, said, “It’s not unusual, but frankly I think it sometimes slows things down.”

Monarch butterfly expert Dr. LIncoln Brower, who joined with the Center for Biological Diversity and Center for Food Safety in filing the petition in August of 2014, was among the first to share the news on the DPLEX email list, a listserv of about 800 Monarch butterfly enthusiasts, scientists and citizen scientists.

In sharing the news, Dr. Brower pointed out how powerful the petition has been in galvanizing support for Monarch butterfly and pollinator habitat.  It has stimulated “all sorts of positive national and international actions to help what is an increasingly serious problem,” wrote Brower.

Commercial butterfly breeders, who oppose clauses in the petition that support an end to the commercial breeding and shipping of Monarch butterflies, took the news in stride.

“Lawsuits resulting from an impassioned and hot button issue such as Monarch butterflies come as no surprise,” said Kathy Marshburn, president of the 100-member International Butterfly Breeders Association (IBBA), a trade association for those who make a living breeding and selling butterflies.

The Association for Butterflies, another butterfly breeding interest group of 81 commercial and hobbyist breeders (including me), quickly relayed the news to its membership which provoked a general consensus that “the lawyers” will be the only winners in the saga.

The petitioners believe that commercial breeders release diseased butterflies into the wild population, potentially damaging it.  In particular, the Monarch-centric spore, Ophyrocystis elektroscirrha (OE), poses a special threat. OE thrives in conditions where the butterflies congregate in large groups, are crowded (presumably as in breeding operations), and/or where milkweeds overwinter.  Recent studies by University of Georgia scientists raise concerns that OE spores, which transfer from the butterflies to their milkweed host plant,  will be consumed by and infect subsequent generations of caterpillars, carried into the next season, and ultimately, jeopardize the migration.

Yet scientists agree that OE already is present in the wild population, just as Streptococcus, the nasty sore throat-causing bacteria, is present in the human population. Scientists use a 1-5 rating system to determine the extent to which a Monarch butterfly is infected.  On her Monarch parasites webpage, OE expert Dr. Sonia Altizer and her University of Georgia team recommend destroying any Monarchs which are infected by putting them in the freezer for an hour.

Both the IBBA and the AFB have taken steps to educate their memberships about best practices for raising healthy, OE-free butterflies in response to the petition.

ibbaIBBA President Marshburn relayed that courses given by Monarch scientists Dr. Sonia Altizer and Dr. Jaap de Roode have been provided to IBBA members at no charge.  Coaching calls by the IBBA’s most experienced breeders and discounts for pathology screenings are also offered.

The AFB has also worked to educate its membership. President Tatia VeltKamp shared plans for a voluntary OE pupae screening with an independent lab as well as a seal farmers can earn and display on their websites when they complete a four-week disease course.

Education is a step in the right direction, but commercial breeders need to be more aggressive in creating some kind of mandatory self-regulation to ensure healthy livestock don’t damage the wild population.  Independent random OE testing of commercially bred butterflies would go a long way toward assuaging concerns.  The USDA already regulates the transport of butterflies across state lines, requiring shipping permits and forbidding certain species where they are not native.  But OE demands a special check.

Another option would be to have an independent firm inspect and certify OE free environments at farms. Findings would be published online and butterfly buying customers could choose the reputable “clean” breeders before making a purchase.

Presumably, breeders could also charge more for OE-free certified butterflies—like organic produce. To offset extra costs, breeders could increase prices or suggest a voluntary additional charge on each order. Monarch butterflies typically cost $7.50 and up retail,  depending on availability, time of year, and number ordered. Shipping charges also apply.

I admit to having a soft spot for commercial butterfly breeders. For a brief time, I wanted to become a breeder and joined the IBBA. I got to know this wonderful group of butterfly enthusiasts and learned to respect the challenge of breeding healthy butterflies on deadline.  It’s hard work.

In addition, every butterfly breeder I met through these organizations gravitated to the business because of pure passion for butterflies and a desire to share it.

There’s a place in Monarch butterfly conservation for commercial butterfly breeding. The magic, education and joy that result from the tactile experience of the inter-species connection of butterfly release events and education have the capacity to touch people and make them care.  Interacting with Monarchs in a tactile way serves as one of the most powerful tools in the conservation arsenal.  It should not be reserved only for scientists, professionals, or those with access to wild milkweed patches and gardens, which is what would happen if commercial butterfly breeding were outlawed by the petition’s enactment.  City kids would be completely cut out of this experience if the Monarch becomes listed. And that would be a shame.

Continued lethargy by the IBBA and AFB on self-regulation will contribute to more scrutiny of commercially bred butterfly livestock and could result in more government regulation of their industry.   At best, inaction fosters a PR problem; at worst, it spells the demise of their industry.

Meanwhile, this focus on professional breeders does nothing to address the many butterflies raised at home by people like me who know way less about clean breeding than those who make their living from it.  Based on personal experience and from the active exchanges on the DPLEX list, thousands and thousands of butterflies are raised and released by hobbyist enthusiasts each season. Do those rearing at home bleach their caterpillar cages, wear disposable plastic gloves, provide each caterpillar with their personal container?

Few of these home-reared butterflies, if any, are checked for OE.  Even if Monarchs are listed, I can’t imagine people stopping this practice, which would limit enthusiasts to 100 butterflies per person/per year.  That suggested number increased from 10 per year in the petition after much public outcry.  I agree with Dr. Brower that the petition has done much to galvanize interest and support in Monarchs and other butterflies–including raising them at home.

The reasons for the general decline of Monarchs are well documented: genetically modified and herbicide tolerant crops, continued urbanization and habitat destruction along the migratory path, illegal logging in Mexico, climate change, and pesticide use.  Is OE, one of many diseases and natural threats to Monarchs and other milkweed feeders a major factor in the Monarchs’ decline?

Some scientists think so.  Dr. Andy Davis, who is married to Dr. Sonia Altizer, has stated emphatically that the Monarch butterfly is not endangered but that he supports the petition because he thinks OE is the number one threat to Monarchs.

In a recent blogpost on his extremely readable MonarchScience blog, Davis stated: “That’s right, the Monarch declines are not a sure thing.”

In a November 7, 2015 blogpost headlined Why I signed the petition to list Monarchs, even though the evidence for declines is shaky, Davis laid out his logic for supporting the petition. “If I don’t think Monarchs are declining, why did I sign it? It was actually because of a small clause that was buried in the fine print – that stated if the listing was enacted, it would become illegal for people to rear more than 100 Monarchs.”

Davis is adamantly opposed to people raising Monarch butterflies in large numbers because he feels that OE is the number one threat to the Monarch migration. As the contentious debate to answer that question continues, commercial breeders could make a huge contribution to the cause by developing credible ways to eradicate OE in their livestock.

Texas Comptroller’s office provides update on Monarch butterfly research, ESA status

About 35 people attended the second Monarch Butterfly Task Force working group meeting in Austin on Thursday, December 17, to hear updates from the Texas State Comptroller’s office on the status of research and assessing whether or not to recommend the Monarch butterfly be listed as “threatened” under the Endangered Species Act.

In Texas, the Comptroller’s office oversees the Interagency Task Force on Economic Growth and Endangered Species. It’s charge: assist landowners, industries and local communities in working with endangered species issues and assessing their economic impact on the state.  Annual $5 million appropriations approved by the Texas Legislature fund the effort, lead by Dr. Robert Gulley of San Antonio.

Since the Monarch butterfly was submitted for consideration as a “threatened” species under the Endangered Species Act in August of 2014, research surrounding the ramifications of such a listing falls under the Task Force’s jurisdiction.

Dr. Gulley warmly welcomed the crowd with the prediction:  “I think we’re in for a very interesting meeting.”

And it was.  Dr. Janis Bush of the University of Texas at San Antonio kicked off the 9 AM session with updates on the $300K research grant awarded her in June to inventory milkweed, the Monarch butterfly host plant, in the state of Texas.

The Lone Star State has been deemed critically important to the health of the Monarch butterfly migration since the butterflies must pass through the “Texas funnel” coming and going on their epic migration to and from their roosting grounds in MIchoacán in the spring and fall.  Monarchs often lay the first generation of eggs in the multigeneration migration here; in autumn, they use Texas as a major nectar stop for fueling their long journey.

About 24 UTSA research associates, students and volunteers have already completed two milkweed surveys under Dr. Bush’s direction–one in July and another in October-November.   The study’s east-west transect stretches from PIneland to Ozona and the north-south from Wichita Falls to Alice.  Field crews stopped every 10 miles to survey the roadside for milkweed over several days. The research hopes to replicate the first such survey done by Dr. William Calvertt in 1996.

“This is just a snapshot in time” Bush said more than once.  She also mentioned that the “pattern between precipitation and milkweed is not clear….If you increase the amount of moisture in Austin, you don’t increase the number of hectares [of roosting Monarch butterflies} in Mexico.”

The UTSA team is also growing a lot of milkweed at a newly constructed UTSA greenhouse, said Bush–six native species as well as the controversial Monarch butterfly favorite, Asclepias curassavica, commonly known as Tropical milkweed.   The team aims to better understand what species Monarch butterflies prefer, seed viability and germination rates, soil, light and nutrient requirements, and drought tolerance.

Bush said she was surprised to learn that rats eat milkweed, something that butterfly breeders and Monarch butterfly enthusiasts have noticed for years.  Two different kinds of rats–a native cotton rat and nonnative Norwegian rat–made unwelcome visits to UTSA’s newly constructed milkweed greenhouse and decimated the plants.  “We don’t know if they got sick,” said Bush, alluding to the bitter-tasting cardiac glycosides found in milkweed that make Monarch butterflies unsavory to predators, “but they seem to like it.”

The UTSA research will also take a look at fire ant impacts on Monarchs and land management best practices.   For example, what effect does mowing have on milkweed?  How does milkweed respond to burning?  Bush also shared with the group San Antonio’s recently named status as the first and only Monarch Champion city by the National Wildlife Federation.  Mayor Ivy Taylor signed the NWF’s Mayor’s Monarch Pledge last week, making San Antonio the first city to adopt all 24 NWF recommended actions that aim to preserve and increase pollinator habitat.

“I’ve never seen the excitement for a species that I’ve seen with the Monarch,” said biologist Russell Castro of the USDA National Resource Conservation Service (NRCS), following  Dr. Bush.  Castro described the NRCS Monarch Butterfly Habitat Development Project, which works with private landowners to increase pollinator habitat in Texas.  Budgeted for $4 million nationwide in 2016, “not that much money for Texas when you get down to it,” said Castro, “Monarch butterflies are the best thing going for conservation on the ground.”

Then Katie Latta, USFWS Monarch Outreach Specialist, took the podium to offer a quick update on the status of the Monarch’s endangered species status listing.

At the moment, we are in the status review phase, which means USFWS is reviewing information and research to determine whether or not the listing of the Monarch as “threatened” is warranted. At some time in 2017 or 2018, USFWS will rule whether the listing is warranted or not.  Lawsuits could delay the process further, or make the listing happen more quickly,  she said.

Finally, the session closed with Cary Dupuy of the Comptroller’s office explaining future funding opportunities and likely areas of research focus.

Sometime in early 2016, a Request for Proposal will be circulated and published in the Texas Register inviting public universities to apply for grants. (Gulley pointed out that the Comptroller’s office is not obliged to issue RFPs, but in the interest of transparency, is doing so.)  Subjects likely to be given serious consideration include best ways to eradicate red imported fire ants, as well as research on answering the intriguing question: “What’s going on with the fifth generation of Monarchs?” said Dupuy.

For years scientists believed that Monarch butterflies migrating to Mexico late in the season were not reproductive.  Conventional wisdom said migrating Monarchs  suspended reproduction to conserve energy for the long flight to Mexico by assuming diapause, which is a state of suspended development of the reproductive organs.

Yet many of us have witnessed late season Monarchs engaging in reproduction as well  laying their eggs on any milkweeds they can find, often bearing fifth and sometimes sixth generation offspring well into November and sometimes December.

This information has been collected anecdotally and through various citizen science efforts, including the Monarch Larvae Monitoring Project and Monarch Watch.  Dupuy suggested that scientific research would be helpful in determining the reality of the situation. Do the offspring of those late season Monarchs migrate, or do they become local residents?  With climate change and more milkweeds available later in the year, the question will become even more interesting.

Monarch Champion status NOT “just talk,” will change how San Antonio manages land

Wednesday, December 9 was a banner day for Monarch butterflies and all pollinators in San Antonio, Texas. That’s when Mayor Ivy Taylor announced that the Alamo City has been named the first Monarch Champion in the country by the National Wildlife Federation (NWF).

Standing before a group of pollinator enthusiasts at City Hall and wearing stylish Monarch butterfly wing earrings, Mayor Taylor shared the proclamation that commits our city to adopting all 24 recommended actions cited by the NWF in their nationwide initiative known as the Mayor’s Monarch Pledge.

“I am pleased that we have set the bar so high in our efforts to attract and care for one very important set of visitors, migrating Monarch butterflies,” said Mayor Taylor in a prepared statement.

That high bar means San Antonio can expect more citizen science projects, a pollinator garden at City Hall or another highly visible public space, more pollinator-friendly landscape ordinances and city mowing schedules, and my personal favorite–a butterfly festival.  Insecta Fiesta, anyone?

We’re talking changes in building codes, recommendations for landscaping by the City’s Sustainability Office and increased grassroots activities like city-sanctioned native plant sales and seed exchanges.

Doug Melnick, Chief Sustainability Officer for the City of San Antonio, said the Mayor’s Pledge is not “just talk.” It will bring about real change. “This will positively impact how we manage city-owned land,” he said.

“I hope to see a citywide conversion of useless streetside inferno strips to Antelope horns milkweed,” said another city staffer who works for our award-winning water utility, SAWS.  The staff person referred to the overheated and challenging-to-landscape swatch of land found between a city sidewalk and the street.   SAWS has done much to raise awareness of native, pollinator-friendly plants through its GardenStyleSA website and WaterSaver coupons that offer rebates to those who replace water-guzzling  turf with native plants.

The timing couldn’t be better, said Melnick.  The City is currently developing three plans under the umbrella of SA Tomorrow: Comprehensive, Sustainability, and Strategic Multi-Modal plans. “We have a great opportunity to further the protection of Monarch butterfly habitats and enhance our biodiversity by incorporating these key strategies into our plans, which will provide a framework for growth through 2040,” he said.

NWF officials were “stunned” by San Antonio’s commitment, said Grace Barnett, NWF Monarch outreach coordinator who works out of Austin for the Washington, D.C. conservation group. In fact, after Mayor Taylor signed the Pledge on Monday, Dec. 7, NWF had to arrange a quick conference call to come up with a new category of support: Monarch Champion. “No one expected a city to take on all of the potential actions associated with the Pledge,” said Barnett.

To date, 46 cities have signed up for the national campaign to encourage mayors and local governments to increase Monarch butterfly and pollinator habitat.

Seven cities including Austin, Dallas, and St. Louis signed the Pledge and agreed to adopt eight or more of the 24 items to join the “leadership circle” of Monarch Mayors. Another 38 cities agreed to do three of the items. Only San Antonio agreed to 24 of 24. See the full list.

As those of you that read the Texas Butterfly Ranch well know, Monarch butterflies migrate each spring and fall over multiple generations, moving from Mexico to Canada and back before settling into their roosts for the winter in the mountainous forests west of Mexico City. At the beginning and end of their journey, they pass through the “Texas funnel,” making our part of the world especially strategic to their migration. San Antonio lies in the heart of that migratory path and often serves as the first stop on the migration north in the spring and as the last stop in the funnel south in the fall.

In recent years, the Monarch butterfly migration has declined dramatically–by 80% from the 21-year average across North America, according to the pollinator advocacy organization the Xerces Society.  Scientists attribute the decline to habitat loss, the increase in genetically modified crops in their primary breeding zone in the Midwest, increased pesticide use and climate change.

In August of 2014, several organizations submitted a petition to list the Monarch butterfly as a “threatened” species under the Endangered Species Act. The petition is under review. In May of 2015, President Obama announced a National Pollinator Strategy that addressed not only the decline of Monarch butterflies, but the demise of bees. The 58-page document also committed the federal government to restore seven million acres of pollinator habitat over the next five years, with a special focus on the IH-35 corridor.

All that focus on Monarchs and pollinators has made San Antonio’s long commitment to pollinator advocacy ripe for the Pledge.

Volunteers like Mary Kennedy, Kip Kiphart and Mobi Warren have worked tirelessly with the Monarch Larvae Monitoring Project (MLMP), a citizen scientist initiative developed at the University of Minnesota.   Local MLMP volunteers have meticulously inventoried natural cycles of milkweeds (the Monarch host plant), eggs, caterpillars, chrysalises and butterflies at Cibolo Nature Center and the Museum Reach Milkweed Patch for years.

Just a short walk south of the Pearl on the San Antonio River, San Antonio’s Milkweed Patch serves an important inland urban monitoring site for overwintering Monarchs and has been the site of research conducted by some of the top Monarch scientists in the country, including Dr. Karen Oberhauser of the University of Minnesota and Dr. Sonia Altizer of the University of Georgia.

Some of us in the San Antonio area tag Monarch butterflies in the fall, as part of the Monarch Watch citizen science tagging program based out of the University of Kansas at Lawrence. Butterflies tagged in San Antonio and the Texas Hill Country have been recovered in the mountains of Michoacán, proving migratory patterns and providing data for scientists. (Personally I have tagged more than 2,000 butterflies, with 27 recoveries.) Programs and pollinator gardens have been established via Phil Hardberger Park, San Antonio Botanical Garden, Mitchell Lake Audubon Center, the Native Plant Society and elsewhere, as well as at community and private gardens all over town.

That’s not to say we’re limited to citizen science in San Antonio. A recent $300K grant awarded UTSA by the State Comptroller’s Office to perform a statewide milkweed survey also contributed to our Monarch Champion status.  Combine that with our unique geographic location, special relationship with Mexico (the winter home to the mariposa monarca), the work of SAWS and San Antonio River Authority (SARA)  on the Museum and Mission Reach restorations with our passionate volunteers and grass roots efforts,   and San Antonio looks ideally suited to live up to the Mayor’s Monarch Pledge.

For a while, we wondered if it were going to happen.

NWF’s Grace Barnett, Dr. Terri Matiella of UTSA and I met with the Mayor’s office in October requesting that Mayor Taylor sign the Pledge. By doing so, she would have joined mayors in St. Louis, Austin, Grand Prairie, and six other cities along the IH-35 corridor that were among the vanguard to sign up. All we expected was participation–a commitment to three of the 24 items. The Mayor’s office was very receptive, but as is often the case when dealing with city government, nothing happened immediately.

Later we met with the City sustainability office. Joan Miller of the Native Plant Society of Texas joined us.  Again, very receptive. Yet….by early December, cities like Oklahoma City, Houston and Garrett, Texas, (population 800) had signed the Pledge while San Antonio continued to consider its options.

Butterfly advocates speculated as recently as the weekend before its signing that the Pledge was dead. Little did we know that what was taking so long was that the Mayor’s office was working with departments across the City to assure they could come through with all 24 items and make us the nation’s first Monarch Champion city.

In addition to the NWF reccomendations, Mayor Taylor said she is even considering a pollinator garden in her Dignowity Hill front yard as well as at the historic Dignowity Park, which her home fronts.  Whenever you’re ready, Mayor, let us know. Our pollinator posse will bring shovels, spades, native milkweeds and nectar plants to help make it happen.

Q & A: Journey North’s Elizabeth Howard talks tech, citizen science, mass butterfly releases

We’ve all read her bulletins.  From the appearance of the first eggs in March and April to the massive wave of Monarchs pulsing through the Texas funnel in the fall, Elizabeth Howard, 60, keeps Monarch butterfly aficionados apprised of the whereabouts and status of our favorite migrating butterfly.

In 1994, the educator, conservationist, and citizen scientist pioneer founded Journey North, a website and program funded by Annenberg Learner, a division of the Annenberg Foundation devoted to advancing excellent teaching in American schools.  The site offers an app, tracking maps, teaching and curriculum tips, and the call to “Go outside. Explore your own backyard. Get ready to share what you see!”

Journey North has embraced that creed for decades, engaging 60,0000 students, citizen scientists, and naturalists of all ages in tracking seasonal change and wildlife migrations around the world–Monarchs, hummingbirds, whales, eagles and others.  The program encourages people to report sightings of eggs, caterpillars and adults through its website or via the Journey North app.

Howard directs the effort with a fluctuating staff of up to six during peak season from her office in Vermont.  Each week during migration season she spends a day and a half crafting the Thursday Monarch butterfly migration bulletins.  The most time-consuming part, she says, is managing the data which is expertly done by her Journey North colleague, Cindy Schmid.

“With a gentle push from the north wind, the migration began to flow into Texas this week,” wrote Howard in the October 8 newsletter.  “The average roost-size in Texas has been 1,000 Monarchs so far, and numbers should build to peak over the coming week.”

I’ve admired Howard from afar for years, impressed by her relatively early embrace of technology in the service of nature. The celebration of all things tech sometimes seems to steamroll the importance of the natural world.

Trained as a biologist, Howard holds special status as a citizen scientist and advocate.

“I consider myself a citizen scientist — and also a ‘real scientist.’” she said via email. “I’m someone who has learned on the job (and I’m secretly proud of that). I think it’s great that the scientific field can make room for people who take the route I have; experience must be at least as valuable as advanced degrees.”

That attitude has afforded her special stature with many of us. When Howard speaks, citizen scientists listen.

Her newsletter’s recent inclusion of a press release announcing a statement authored by 10 scientists discouraging the purchase of commercially bred butterflies for fear of unleashing the debilitating Ophryocystis elektroscirrha (OE) spore on the wild population gave many of us pause.

Under the headline, “Concern about Monarch releases,” Howard included the press release with a link to the statement accompanied by a quote from Sarina Jepsen, Endangered Species Program Director of The Xerces Society in her weekly newsletter.

“Breeding and releasing monarchs might seem like a harmless activity, something that might even help struggling populations. Unfortunately, the practice holds the potential to actually harm wild monarchs and disrupt research that is critical to their conservation,” said Jepsen.

The Xerces Society, along with the Center for Biological Diversity and Dr. Lincoln Brower, submitted the petition last August to list the Monarch butterfly as “threatened” under the Endangered Species Act.

Howard touches on that and more, below.

1. How did you arrive at the notion of crowdsourcing information about the Monarch butterfly and other migrations?

As a winter-worn resident of the northern US, waiting for spring was always a challenge. Toward the end of winter, I’d follow bird migrations by listening to ‘rare bird alerts’ from the states to my south. (At the time, bird sightings were compiled on telephone answering

machines.) So, when I heard about ‘the internet’ — and how it could connect people — it struck me immediately that the technology could be used to track migrations. I actually remember the instant the idea occurred to me; I pictured a map with lights turning on as migrants arrived successively across the landscape.

2. When you started Journey North in 1994, that was extremely early Internet. Obviously, much has changed since then, but what has been the most astounding or impressive change in the technology and in citizen science?

What’s been most impressive is the pace of change. When we began in 1994 e-mail was new and there was no web. Now we have images, voice, video, social media, apps, ever-increasing band-width and immediate access to people across the planet. I love having had a job that incorporates these advancements so closely and directly. Truly, not a week goes by where we don’t see new and creative applications – and we can build them right into our work.

Follow the migration at Journey North.

As for citizen science, I’m still impressed that we can track butterflies across the continent simply by sharing sightings and that the information is so valuable. For example, we now know that even weekly differences in spring temperatures can impact the subsequent size of that year’s population. Who knew?

3. Are you generally optimistic or pessimistic about the future of the Monarch butterfly migration? Do you think your great-grandchildren will experience it?

I guess I’m optimistic in the short-term but I hate to think about the long-term because conservation work is going to get even harder. The pace of habitat destruction is projected to accelerate and, on top of that, there’s climate change. At a recent meeting scientists were grappling to determine the migration’s “extinction threshold.” We know we’re flirting with it and we don’t know the tipping point.

What’s heartening is the outpouring of support for Monarchs. If people decide it’s important, maybe we can save them.

4. The Monarch butterfly community has been “aflutter” about the possibility of the Monarch’s possible listing as “threatened” under the Endangered Species Act. Where do you come down on this?

If this is what it will take to protect the Monarch migration, I’m all for it. However, I do have questions about how and whether this approach would work.

For example, a landowner might rid his/her property of milkweed out of concern that he/she won’t be allowed to do so later. Any regulation should be written so we can learn as we go and make sure unintended consequences don’t make matters worse.

5. You told me via email once that your favorite migrating creature is a toss-up between hummingbirds and Monarchs. Do you still feel that way, and if so, what is it about one or the other that is most interesting? Also, which species garners the most attention/views on the Journey North site? ( I bet I know the answer to that one.)

That’s right, I can’t choose. Monarchs are perhaps more awe-inspiring; I mean, how DO they migrate to a place they’ve never been? But we can experience hummingbirds on a more individual, personal level. I love their chutzpah; they’re so much fun to have around. Plus, they make me laugh which a Monarch never has.

Hummingbirds surpass Monarch in popularity on Journey North and that fits. Google “hummingbird” and you’ll get 31 million hits compared to the Monarch’s meager 1 million.

Future citizen scientists

Howard is most proud of engaging future citizen scientists like these boys discovering some Monarch eggs on milkweed. –Photo via Journey North

6. What is your proudest moment as the founder of Journey North?

I’m proud that Journey North provides such an easy entry point to citizen science, and that we have brought so many people into the fold. We now have 60,000 participants spread across Canada, the US, and Mexico. People are telling the Monarch’s story, right down to those who live near the sanctuaries in Mexico and announce the butterflies’ arrival. How neat is that?

7. You recently issued a news release discouraging people from buying Monarch butterflies in any form from mass breeders for release in the wild. Do you honestly think that commercial butterfly breeders have no place in Monarch conservation?

In my view, this is about what the monarchs need — we have to put their needs first. The surest way to help monarchs is to provide healthy habitat and leave the breeding to them. If nature’s taught us any lesson it’s that ecological systems are always more complex that we expect. Think of the pictures of millions of monarchs overwintering together — having come from across the continent — and then imagine some carrying a communicable disease. There’s so much we don’t know. I don’t think we can be too cautious.

How to tag a Monarch butterfly in six easy steps

NOTE:  The following post ran in September of  2012, but warrants reposting today.  Happy tagging!

One of the most common questions we get at the Texas Butterfly Ranch is how the heck do you tag a Monarch butterfly?

Ready to tag some butterflies?

Ready to tag some butterflies?

It’s pretty straightforward, really.  You’ll need a butterfly net, a clipboard or mini notebook and a writing utensil to record your findings.   You’ll also need tags issued by Monarch Watch ($15 for 25 tags).    I recommend a hat and camera, too.

Before you go, apply sunscreen or insect spray if you use them, then wash your hands thoroughly.   Monarchs and other butterflies are more resilient than we think, however, Deet, Paba  and other chemical contact with their scales, wings and bodies should be avoided.  There’s no need to sterilize your hands or wear gloves.  Just wash your hands.

Monarch Watch tags and data sheets

You’ll need Monarch Watch tags and data sheets to tag Monarch butterflies. And a butterfly net.

When should you go tagging?  I like late mornings after my second cup of coffee.   By then, the butterflies have had a chance to warm up their bodies and are out flying and nectaring.  Remember, butterflies won’t fly if the temperature is less than 60 degrees, so late mornings and afternoons on sunny days are ideal.   Right before sunset is good, too, especially when they’re migrating.  In the Hill Country in October, masses of Monarch butterflies will often drop from the sky around dusk and look for roosting spots—usually in protected tree limbs and often near water sources.

Ready for some tagging?  Here’s how to do it.

  1. Locate butterfly

Millions of migrating Monarch butterflies will pass through the “Texas funnel” on their way to their ancestral roosts in Michoacan, Mexico, over the coming weeks and months.    According to Monarch Watch, peak migration for San Antonio and Austin will be October 2 – 22.

Typically, we see a first pulse of vanguard Monarchs around Labor Day in the Hill Country and in our San Antonio and Austin gardens.  In September we’ll consistently see individual Monarchs trickling through town.  By October, groups will show up and form evening roosts in trees and large bushes like Poverty Weed along our rivers and other protected locations.

The best places to see them are along our streams and rivers where late season blooms offer a nectar rich rest stop.  Monarchs fuel up on their journey south, so anywhere with late season butterfly-friendly flowers—native and Tropical milkweeds, Gregg’s Purple mistflower, Cowpen daisies, Frostweed, Goldenrod, lantana, for example—should draw them, as well as other butterflies.

Your own garden, if it has butterfly-friendly flowers blooming, should draw Monarch butterflies.  Look, observe, wait.   And be patient.  For some prime Monarch butterfly spotting, stop by the Milkweed Patch along the Museum Reach of the San Antonio River this fall.

2.  Net butterfly

Netting a Monarch butterfly—or any butterfly for that matter—is more challenging than it looks. The flitting creatures exhibit extreme skittishness and their compound eyes afford them a 360-degree field of vision. The slightest movement can send them sailing.

When I first started tagging Monarchs, I diligently chased them in flight. After slipping in the river more than once and skinning my knee after tripping down the steps at my house while in hot pursuit, I resolved to only try and net Monarchs when they’re roosting or nectaring. I’ve witnessed several ace netters with excellent hand-eye coordination, quick reflexes, and a sniper’s aim nab butterflies in flight, but I’m not among them.

It’s easier to net Monarch butterflies when they’re nectaring. Sneak up on them from behind.  Photo by Monika Maeckle

Suggestions:  wear low-key clothing that blends into the environment, move slowly, keep quiet and sneak up on them from behind.  Once you swing your net, the butterflies will scatter.  It resembles fishing in that sense;  when you cast your line, the fish get spooked and flee, but they’ll be back. After a few minutes, the butterflies will resume their activities—nectaring, resting or roosting.  Or they may fly out of your reach.

Once you get a butterfly in your net, be sure to flip the net sock over the circle of the rim—otherwise the clever insects can slip out.   With the net sock folded over the net structure, they will remain in your net.

Some folks take the net down to the ground after they swoop the butterfly into the net to ensure the butterfly doesn’t escape.   This is especially helpful when you capture many at once.

3. Collect butterfly/butterflies from net

Once the butterfly or butterflies are in the net, gently reach in and clasp an individual in your cupped hand, wings folded together if possible.  (No insecticides or sunscreen on your hands, please.)  The butterflies will flail around in the net, so try to calm them by folding their wings closed and gently pressing the net fabric on them. Also, try holding the butterfly upside down;  it seems to calm them.

Keep the net closed so that other butterflies don’t fly out as you remove the one in your grasp, then pull out your catch and take a look.

4.  Examine butterfly, establish its sex.

This is when you examine the butterfly to determine its sex.   Open the wings gently and look for the two pheromone sacs on the lower half of the butterfly’s wings.  If you see two black dots, it’s a male.  If not, it’s a female.   Also note the state of the butterfly—is it

Male Monarch Butterfly

weathered and raggedy, or fresh and healthy?  If the butterfly is extremely worn out and highly unlikely to make it to Mexico, refrain from tagging it.  Let the poor creature fly off.  Note the info on your data sheet or notebook, as well as the tag number.

Raggedy Monarch butterfly

5.  Remove tag from sheet and adhere to butterfly

Holding the butterfly between two fingers with wings closed with one hand, remove a Monarch Watch sticker from the tag sheet.  I like to use my thumbnail and get them on the tip of my nail so they’re easy to slip onto the discal cell of the butterfly’s wing. Some people like to use a toothpick to lift the tag from the paper.

Use your thumbnail to lift tag from sheet and transfer to butterfly.

Place the tag on the discal cell, as illustrated in the tagging sheet sent to you by Monarch Watch.  Press gently, but firmly.  Congratulations!  You’ve tagged a Monarch butterfly.

Press the tag onto the discal cell in the middle of the lower wing, as shown.

Make sure you’ve noted the tag number, butterfly’s sex, any other useful data, on your data sheet or notebook.

6.  Release

Open your grasp and let the butterfly go.  If you’re so inclined, send her off with a kiss and best wishes for safe travels to Mexico.

Off she goes!

After the Monarch migration season, send all your data to Monarch Watch by December 1 so it can be entered into the online tag recovery database.   In the spring, you can check  to see if any of your Monarchs were recovered in Mexico.

Good luck with your tagging.  Please let us know how it goes.

Butterfly FAQ: How to move a Monarch butterfly chrysalis

One of the most frequently asked questions we get this time of year, especially in a rebound season like 2015, is how to move a Monarch chrysalis.

Janine Robin wrote via email last week that she found six Monarch chrysalises in her backyard in Folsom, Louisiana.  “Most are in a safe spot, but two are on a large clay pot. They are secure, but in the afternoon sun for about three hours.  Should they be moved?”

Good question.   That’s a judgement call.   Caterpillars are pretty intelligent about locating their chrysalises in safe places.  But like all of us, sometimes they misjudge.

For example, the Queen chrysalis pictured below formed on the edge of my kitchen door.

Queen chrysalis on door

I didn’t even notice until today (and I looked for her!) when I found a smashed newborn Queen caught in the door.  Sadly, she perished.

So if the chrysalis is in a dangerous or inopportune spot–or, if you just want to witness the magical moment of eclosure, when it hatches–then yes.  Move it.

The tricky part is often getting the chrysalis OFF of the surface to which it is attached without damaging the chrysalis itself.

You may have noticed that before caterpillars make their chrysalis, they are very still and quiet for about a day.  I like to think that they are deep in thought during this transformative stage.  It must take a lot of concentration and mindfulness to morph caterpillar legs into butterfly wings.

But what’s actually happening is they are spinning a vast silk web that you often don’t notice.  If you rub your finger on the surface around the stiff, black cremaster, which serves as a hook to hold the chrysalis in place, you’ll feel a thin, soft layer of silk.  That’s what you need to gather up to remove the chrysalis safely.  See the slide show below to learn how.

How do you know if the chrysalis is in a dangerous spot?

Newborn Monarch butterfly

Consider that the newly hatched butterfly will spend about two hours hanging from its empty chrysalis shell while it’s wet, crumpled wings drop and form properly. It’s advantageous for the butterfly in this delicate state to have something to climb on or cling to–a stick, netting, paper towel, leaves.

Winds blow. Animals or people walk by and brush up on the butterflies–possibly knocking them off. As Janine Robin wrote today, “Of the two chrysalises on the large clay pot, the lower one either fell off or was brushed off by an armadillo, possum or raccoon….I think it’s damaged.” Robin said she was able to reattach the chrysalis with a spot of glue.

Also, if after hatching the butterflies fall and can’t climb back up (which seemingly could happen in the above pot and appears to be what happened with my Queen), their wings will dry crumpled and they will die. Having an easy-to-grab surface or twig/branch/leaf to grab would definitely help hoist heavy, damp wings in the event of a fall.

For more on this subject, see our previous post: Is moving a Monarch chrysalis OK? Yes, and here’s how to do it.

Meanwhile, check out the slide show above to master the tricky task of getting a chrysalis off the surface to which it is attached.  Good luck, and let us know how it goes.
