2014: From Worst Year for Monarch Butterflies to Rebound, Increased Pollinator Awareness

The end-of-the-year provokes a look back to assess progress–if any–on the pollinator front.   2014 held a mixed bag of good and bad news with occasional surprising twists.

We started out thinking 2014 might be the worst year in history for Monarchs given that the 2013 migration ranked lowest in population numbers ever. Remember the headlines?  “90% drop in Monarch butterflies,” read Newsweek, the Washington Post, the New York Times and other media outlets.  But the season surprised us.

A reprieve from the drought, well-timed rains in the Midwestern breeding grounds and milder temps in Texas made for a late summer surge, and an exceptional year for Monarch.  We look forward to hearing the numbers observed in Michoacán this winter.  While this temporary boost won’t fix the longterm, persistent declines caused by pesticide use, genetically modified crops, climate change and general habitat loss, it’s a welcome, unexpected turn.

On the PR front, 2014 couldn’t have been much better in terms of raised awareness.  Pollinator peril has gone mainstream.

The First Lady of the United States planted the first pollinator garden at the Whitehouse.  The presidents of Mexico, the U.S. and Canada agreed to work together to restore Monarch and other pollinator habitat, and some of the top scientists and pollinator advocacy organizations in the country submitted the Monarch butterfly for consideration as “threatened” under the Endangered Species Act.

Simultaneously, professional butterfly breeders gathered to create programs to systematically combat OE, the Monarch-centric spore driven disease that attacks Monarchs and other milkweed feeders.   And a lively debate continues about the appropriateness of planting Tropical milkweed, Asclepias curassavica, the only Monarch host plant commercially available.

Again, while the facts still spell general decline and danger for pollinators, the awareness of the problem has been elevated like never before.  That’s all good.

Below are some of the Texas Butterfly Ranch’s top posts written in 2014 that should give you a good perspective on the year.

Wake-up Call: Monarch Butterfly Numbers Plummet

In February we wrote the dreary news that for the 2013 season, the entire migrating Monarch butterfly population occupied only .67 hectares. That’s 1.65 acres, 72,000 square feet–or about 35 million butterflies, down from highs of 450 million in years’ past. Think about it: the entire population of migratory Monarch butterflies could easily fit into the average Walmart store, with 30,000 square feet to spare.

On April 2,1600 Pennsylvania Avenue added Swamp milkweed, Asclepias incarnata and Butterfly weed, Asclepias tuberosa to its 1500-square-foot vegetable garden. The milkweed species will serve as Monarch host plant as well as a favored nectar source to bees and other butterfly species.  The milkweeds also marked the first time in history that a pollinator garden had been planted at the White House.

Monarch Butterflies Headed our Way in Promising Rebound Season

This year’s migration seemed to start early and end late, with the Monarchs taking their time and reproducing profusely along the way with optimal conditions in their favor.  Here in Texas, our season was 7 – 10 later than usual for peak migration.

Endangered Species Act:  Wrong tool for the Job of Monarch Butterfly Conservation?

Several pollinator advocacy organizations and many famous PhDs support the listing of the Monarch butterfly as “threatened” under the Endangered Species Act.   I, along with many others, do not.   Read this post to decide for yourself if you think it’s truly the right tool for the job.

And just so you don’t think that we’re species-ist at the Texas Butterfly Ranch, I’ll mention that the number one post at the Texas Butterfly Ranch in 2014 was NOT about the Monarch butterfly.  Rather, the mysterious, ubiquitous Black Witch Moth, took the top spot in 2014 for the second year in a row.

Judging from my professional experience in online marketing, I’m betting the popularity of this post, first written in 2012, and updated in 2013, can be attributed to the fact that no one is writing about Black Witch moths–and yet they are amazingly interesting.   Blog posts, like Eastern Swallowtails, have what are called “long tails“–meaning that they generate many views over time.   The longer they are on the web and the more that people read and share them, the more popular they get and the higher they climb in search engine rankings.

This post, smartly headlined, Large, Batlike and Harmless:  Black Witch Moth

includes many keywords that people type into the Google search box, wondering what the heck the enormous moth is doing hanging out in the rafters. It has generated more views than any other this year. The reason it is not featured as a top post is that it wasn’t written in 2014.

Texas Parks and Wildlife Launches Milkweed Monitoring Project

The intersection of technology and Nature continues as the Texas Parks and Wildlife Department (TPWD) announced a program to monitor milkweed stands throughout the Lone Star State this week.

The program, Texas Milkweeds and Monarchs, will be housed on the iNaturalist platform and launches as debate heats up about the wisdom of planting the technically nonnative but widely available Tropical milkweed, Asclepias curassavica, to help restore Monarch butterfly habitat in the face of the insect’s possible listing as “threatened” under the Endangered Species Act.  iNaturalist, a crowdsourced species identification system, declares its mission as “connecting people to nature through technology.”

The crowdsourced Texas Milkweeds and Monarchs project will document and map via observations made by citizen scientists where, how much, and what species of milkweed exists in Texas and whether or not Monarch butterflies are using it.

Since milkweed–that is, any plant in the Asclepias family–is the only host plant on which Monarch butterflies will lay eggs, its presence or absence in our landscape is critical to the migrating butterflies.  Increased use of herbicide tolerant crops and general habitat loss have spelled decline for the once pervasive wildflower.

Mark Klym, Information Specialist in Wildlife Diversity for TPWD, said the project came to fruition because education and outreach folks at the department received “multiple questions per week … about what was happening to the Monarch population, why Texas Parks and Wildlife Department was not treating them as a priority.”  California-based iNaturalist.org ” is quickly becoming the go-to platform for citizen science around the world,” he said.

TPWD began working with iNaturalist about two years ago with a herpetology  tracking project, Herps of Texas,  which now boasts 11,000 observations by more than 500 citizen scientists who’ve documented 95% of the species in Texas, said Cullen Hanks, Texas Nature Tracker Biologist for the department.  Hanks, who manages the relationship with iNaturalist, said the platform was chosen because it had a lot of the functionality needed to track and harvest “taxa data,” which is information about classifying species via their taxonomy.  (NOTE:  If you’re wondering, herpetology is the study of amphibians and reptiles.)

TPWD already has the herps project, and also a Mammals of Texas, Birds of Texas and now their first plant-tracking project, the Milkweed and Monarchs project.  Check out all the Texas iNaturalist projects.

“Sounds like a neat effort to identify key milkweed habitats in Texas,” said Monarch and milkweed scientist and PhD candidate Dara Satterfield, whose dissertation includes research on the relationship between Monarch health and Tropical milkweed, upon hearing about the partnership.  Satterfield cited milkweed mapping as a long-term goal of the conservation plan being developed by Monarch Joint Venture.

To participate, volunteers can download the app on their phone or computer. After creating a login, choose the Texas Milkweeds and Monarch project, and start contributing observations in the form of text, photos, video–even audio clips.

The process works a bit like the Journey North program which invites volunteers to contribute observations of Monarch eggs, larvae, butterflies and roosts, geolocates the observation, and maps them in real-time resulting in a constantly updated map/picture of Monarchs in all their stages.

Texas Parks and Wildlife hopes to map milkweed throughout the Lone Star State via the iNaturalist app.

Contributors will be asked four brief questions about their observations, but don’t need to know specifics of the 40+ milkweed species found in Texas.  They can simply type “milkweed” and ask for assistance in identifying the plant, states the news release.

Q & A: Grad Student Dara Satterfield on Tropical Milkweed and Monarch Butterflies

Graduate student Dara Satterfield caused quite a flutter recently when she was featured in the New York Times as the co-author of a study looking at how Tropical milkweed, Asclepias curassavica, may be effecting the health of Monarch butterflies and their Pan-American migration.  Her dissertation focuses on the relationship between migration and infectious disease in wildlife, with Monarch butterflies as her species focus.

In the article headlined For the Monarch Butterfly, a Long Road Back, and promoted heavily online as “Monarch Butterflies:  Loved to Death?” science journalist Liza Gross explored the pros and cons of planting Tropical milkweed.   To read our original story on this topic, check out Tropical Milkweed:  To plant it or not, it’s not a simple question.

Satterfield, a PhD candidate at the Odum School of Ecology at the University of Georgia, and other scientists speculate that Tropical milkweed, the most widely available but technically nonnative milkweed and favorite host plant of the Monarch butterfly, may be damaging the Monarchs’ abilities to stay healthy, on track and make their way to Mexico.

“She and her graduate adviser, Sonia Altizer, a disease ecologist at Georgia, fear that well-meaning efforts by butterfly lovers may be contributing to the monarch’s plight,” said the article.

I caught up with Satterfield recently to ask questions that have arisen since the article posted on November 17.   She expressed concern that the NY Times article might have confused some readers–and no doubt the issue is confusing and complex.   Hopefully the Q & A below will clarify matters a bit.

Q: I’ve talked to several scientists that insist that Tropical milkweed is the plant on which Monarchs evolved. Do you agree with that?

A:  Good question. From what I understand, the historically held view was that Monarchs evolved from a tropical ancestor from Central or South America, and so some scientists have said they must have used Tropical milkweed and other exotic milkweed species early in their speciation.

New evidence suggests a different story. The recent Nature paper examining Monarch genetics revealed that, actually, Monarchs appear to have originated in North America (and would have evolved on native North American milkweed species) and the other Monarch populations in Central America, South America, the Pacific, etc. (some of which would use Tropical milkweed) came from the North American population.

Q. You have said that Monarchs are much more likely to be sick in places where Tropical milkweed grows year-round–but is it really Tropical milkweed (Asclepias curassavica) that is the problem? If Common milkweed (Asclepias syriaca) or Swamp milkweed (Asclepias Incarnata) also survived a winter and were available, would the same tendency apply?

A. You are correct, I think. The same disease problem would probably occur with any milkweed species that grew year-round in warm areas and was attractive to Monarchs. It just happens that Tropical milkweed is the species that does stick around. We don’t think Tropical milkweed itself is bad; it’s the year-round growth that is harmful because it promotes disease.  Also, I’d just like to add that we would not even understand this problem without the help of dedicated volunteers and citizen scientists who share observations and collect data. Much of what we know about Monarch ecology can be attributed to the help of citizen scientists.

NOTE from Texas Butterfly Ranch:   Thus, best practice suggests slashing all milkweeds to the ground in late fall if they do not die back from freeze.  This prevents OE spores from building up and spreading disease.

3. What is the purpose of a migration? If everything an insect needs to complete the life cycle is available locally, what interest is there for the insect to migrate?

For most migratory species, the purpose of migration is to track seasonal changes in climate or resources needed for survival and reproduction. Without human interference, migration as a strategy can often support large numbers of animals, because migratory animals may take advantage of the best resources–in different parts of the world at different times of the year (e.g., red knots that travel from the North Pole to the South Pole to experience summer in both hemispheres).

DSC00035

But some migratory populations including birds, bats, fish, and hoofed animals are altering their migrations–shortening or halting their journeys–in response to human activities like barriers in their migratory pathways (e.g., dams), changes in climate, and human-provided foods. Examples of this abound (No Way Home, by David Wilcove). Of course some of these newly non-migratory animal populations will be just fine and learn to adapt to new circumstances, but others will not.

Consequences will include changes in infectious diseases, loss of ecosystem services associated with migration (e.g., nutrient transfer between ecosystems by salmon, control of insect populations by birds), and in some cases, species extinction.

For Monarchs specifically, their migration allows them to have a large population capacity. If Monarchs solely engaged in winter-breeding, rather than overwintering in Mexico, this strategy could likely only support a much smaller population. So we try to conserve the abundance of migration.

Of course, individual animals operate on an individual basis and do not make choices based on what is best for the population at large, so individual animals will often take advantage of resources that are available to them–for example, why go to Mexico when I have everything I need here?

The problem with that, in this case of year-round milkweed and year-round Monarch breeding, is extremely high levels of protozoan disease as well as risks of winter starvation (running out of Tropical milkweed) and freeze events that kill caterpillars. The concern is also that migratory Monarchs (or their offspring) might be exposed to parasite-contaminated milkweed in the spring.

All of that said, Dr. Chip Taylor is correct that the link between year-round milkweed and disease is by no means the largest threat to Monarchs. However, given what we now know about this problem, we have the opportunity to reduce disease in Monarchs by keeping milkweed seasonal rather than available all year.

NYTimes, Commercial Butterfly Breeders Raise Awareness of OE to Help Monarchs

In the last two weeks, both the New York Times and professional butterfly breeders have made progress in raising awareness of a little known but possibly significant factor in the decline of the Monarch butterfly migration–a spore driven, Monarch-centric disease known as OE.

OE Spores with Monarch Butterfly Scales

Ophryocystis elektroscirrha, known in the Monarch community as OE, infects Monarchs and other butterflies that host on milkweed, sometimes resulting in butterfly crippling or death. Spores transfer from creature to creature via physical contact with each other or the plants on which they rest or eat, thus scientists worry that local OE-infested Monarchs will infect populations that are passing through, possibly jeopardizing the migration.

Several sessions at the Butterfly Professionals Conference held in Ft. Lauderdale, Florida, November 12 – 16, were dedicated to educating about 100 attendees on prevention of the disease.   The organization has been called to task in the recent petition to list the Monarch butterfly as “threatened” under the Endangered Species Act for releasing butterflies that could carry OE into the wild population.

Connie Hodsdon, a butterfly breeder and owner of Flutterby Gardens in Bradenton, Florida, addressed the joint meeting of the International Butterfly Breeders Association (IBBA), the Association for Butterflies (AFB) and the International Association of Butterfly Exhibitioners and Suppliers (IABES), in a 90-minute session focused exclusively on OE.

“You have to start clean and stay clean,” said Hodsdon before sharing slides of mottled, dark speckled OE-infected Monarch chrysalises.  She then launched into a detailed description of the methodology she employs for preventing or eliminating OE from butterfly livestock.

Her approach includes multiple bleach baths of Monarch eggs, breeding vessels, and all plant material in a special product imported from Great Britain called Milton, separate rearing rooms for different broods of butterflies, and regular testing with a microscope for OE spores.

“We have to do everything in our power to make sure our Monarchs are an asset to the species,” Hodsdon told the conference crowd.  “If you can’t, find another species to raise.”

Later, butterfly breeder Edith Smith, owner of Shady Oak Butterfly Farm in Brooker, Florida, continued the call-to-action for breeders to be meticulously clean in their operations and monitor livestock closely–not just for OE, but for more pervasive and difficult-to-cure plagues.

Edith Smith

Smith, who teaches various workshops and seminars about butterfly diseases that nature uses for population control, has been raising butterflies commercially since 1999.   She proposed that OE should be eliminated before it even enters the breeding operation.

“These are diseases that butterfly breeders must keep out of their breeding facilities,” she said.

Both Smith and Hodsdon keep a 100x microscope on hand along with clear, invisible tape. They check Monarch and Queen butterflies for OE spores by rolling the abdomen of young butterflies along the tape, then viewing the tape under the microscope. If football-like spores are prevalent, the butterfly is destroyed rather than used as a breeder or sold as livestock.

“If this is done and any milkweed that wild butterflies can touch is disinfected, OE shouldn’t ever be an issue,” said Smith.

A week after the IBBA Conference, the New York Times caused a storm with citizen scientists and butterfly gardeners by focusing on possible negative impacts of planting Tropical milkweed to attract Monarch butterflies.  Some scientists believe that planting Asclepias curassavica, Tropical milkweed, outside certain ranges creates hotbeds of OE that could negatively impact the population and the migration. Monarchs will only lay eggs on their host plant, which is any member of the Asclepias species.

In an article headlined For the Monarch Butterfly, a Long Road Back, and promoted heavily online as “Monarch Butterflies:  Loved to Death?” science journalist Liza Gross explored the pros and cons of planting Tropical milkweed.   To read our original story on this topic, check out Tropical Milkweed:  To plant it or not, it’s not a simple question.

The article featured an interview with Dara Satterfield, a PhD student at the Odum School of Ecology at the University of Georgia.  A native of Marietta, Georgia, Satterfield’s dissertation focuses on the relationship between migration and infectious disease in wildlife. Monarchs are her species focus.

Dara Satterfield

Satterfield works closely with Monarch scientist Dr. Sonia Altizer, the foremost expert in the country on OE. (NOTE:  Dr. Altizer recently hosted a webinar for commercial butterfly breeders on how to prevent OE at their farms.)

This is the line that really whipped up butterfly fans:  “…Well-meaning efforts by butterfly lovers may be contributing to the Monarch’s plight.”  The piece then stated that planting Tropical milkweed, the only Asclepias species available commercially, might be doing more harm than good because it might cause butterflies to stick around, not migrate and spread the OE spores year-round.

Confused?  Are you wondering what to plant when scientists and conservationists encourage us to help Monarchs by planting milkweed, yet when we do, we’re told it promotes a deadly Monarch butterfly disease?

Me, too. What’s a butterfly gardener to do? I tracked down Satterfield to provide direction.

“The monarchs are showing us something…and the pattern is clear and consistent,” Satterfield said via email, explaining that Monarchs are much more likely to be sick in places where Tropical milkweed grows year-round.

“In a nutshell, this is how we would summarize for gardeners: Choose native milkweeds whenever possible,” she said.  Satterfield insists that Tropical milkweed should be limited in areas where it might survive the winter–coastal Texas, California, Florida, for example.   Overwintering of the plant enables winter-breeding and high levels of OE infection, she contends.

She recommends if you DO plant Tropical milkweed in a place that rarely freezes, best practice would include cutting the plant to the ground so as not to harbor overwintering OE spores.

For the record, consensus on the science of how Tropical milkweed effects or not the Monarch migration is as elusive as the butterflies themselves.   Dr. Chip Taylor of Monarch Watch told the New York Times that Tropical milkweed constitutes “a tiny, tiny portion” of the milkweeds encountered by Monarchs returning in the spring.  “Should they be there? Probably not. But will they do immense harm? Probably not.”

But, to play it safe, slash that Tropical milkweed to the ground this winter if a good freeze doesn’t do it for you.

Endangered Species Act Petition: Wrong Tool for Monarch Butterfly Conservation?

As Monarch butterflies finished their tardy, impressive sweep through Texas in early November demonstrating a 2014 population rebound, those in the Monarch community debated the wisdom of listing the iconic migrating butterfly as “threatened” under the Endangered Species Act (ESA).

In late August, the Xerces Society, Center for Food Safety, Center for Biological Diversity and Dr. Lincoln Brower submitted this petition to the Secretary of the Interior requesting the Monarch butterfly be listed as “threatened” under the ESA.

This year’s seemingly healthy population, predicted by experts to be two, perhaps three times as large as last year’s record low, is a welcome turnaround from the post-2010 decline associated with the prolonged Texas drought and other challenges to the migration. The rebound has created a bit of a disconnect, arriving the same year as the petition to consider the iconic migrants’ threatened status.

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. The ecosystem that supports the Monarch butterfly migration–and pollinator habitat in general–is tattered.  Dr. Chip Taylor stated it well in a recent blog post: “Monarchs clearly aren’t endangered. As this discussion proceeds, we need to make it clear in all communications that it’s about the migration and not the species per se.”

Agreed.

So, is petitioning the federal government to list our favorite butterfly as “threatened” the best way to accomplish that goal?  After giving it much thought, I think not.

Threatened status might motivate large corporations and government agencies to be more considerate of Monarchs and other pollinators, but for private citizens with no government or scientific affiliation, such status could be counter productive.

As one who enjoys Monarchs visiting my urban garden eight months of the year and roosting along the Llano River in the fall, I take particular issue with the federal government telling me what I can do with my land.

Milkweed and nectar plants fill my San Antonio pollinator gardens.   We’ve also undertaken a riparian restoration in the Texas Hill Country where Monarchs roost each year, an effort that includes planting native milkweeds and other nectar plants along our riverbanks along the Llano River.

In the course of any given year, I raise several hundred butterflies, not just Monarchs, for fun, joy, and to give as gifts. My goal is to inspire appreciation and understanding of our outdoor world and reinforce the majesty of nature in a small, everyday way.

According to the 159-page petition’s final line,  if “threatened” status is approved, such activities would be a crime.  People like me and you will be allowed to raise “fewer than ten Monarchs per year by any individual, household or educational entity”–unless that activity is “overseen by a scientist, conservation organization, or other entity dedicated to the conservation of the species.”

This seems to strike at the very heart of what has made the Monarch butterfly so iconic and widely embraced–the crowdsourcing of understanding its migration and the groundswell of interest in conserving it.

Catalina Trail, then known as Cathy Aguado, was the woman on the cover of National Geographic in 1976

Citizen scientists and individuals like Catalina Trail were instrumental in the discovery of the Monarch roosting spots in 1976.  File photo.

Let’s not forget that regular folks like us helped piece together the puzzle of the Monarch migration back in 1976 through Dr. Fred Urquhart’s monitoring project and the intrepid explorations of individuals like Catalina Trail, the first person to chance up on the roosts in Michoacán.  Making lawbreakers of regular folks for participating and reserving that privilege only for scientists would do more harm than good.

If milkweed becomes part of critical habitat as defined by the ESA under this petition, that would mean destroying milkweed–or getting caught destroying it–would become a crime punishable by fines or mitigation.   Civil penalties can come to $25,000 per ESA violation and criminal fines up to $100,000 per violation, and/or imprisonment for up to one year.

Many landowners will simply not plant milkweed or will do away with it entirely just to avoid problems.  In some parts of the universe, this is known as Shoot, Shovel and Shut-up, the “practice of killing and burying evidence of any plants or animals that might be threatened or endangered.”   We have seen this attitude first hand in Texas.  Ranchers have been known to destroy first growth Ashe Juniper to preserve grass lands and conserve water to avoid ramifications of disturbing the preferred habitat of the endangered Golden-cheeked warbler.

Also, the U.S. Fish and Wildlife Service is cited as the enforcement agent for these rules– but how likely is it that agency personnel will have the bandwidth to do so? If enforcement is not practical, what is the point of the rule?

The petitioners take special issue with the commercial butterfly breeding industry, which supplies eggs, caterpillars, chrysalises and live butterflies for schools, nature exhibits, conservation activities and events. The petition specifically details how conservation education activities like the rearing of Monarchs in school classrooms or at nature centers will be immune to regulation, “provided that the Monarchs are not provided by commercial suppliers.”

That means if a teacher in a classroom or home school situation in New York City wants to teach metamorphosis to fifth graders using Monarch butterflies, she can only do that with  butterflies personally harvested in the Big Apple. The best intentions often lead to unintended consequences, and that is what I fear in this instance.

“If only wild caterpillars can be collected and brought into the classroom, we will run the risk of excluding urban children…. precisely what we don’t want,” Dr. David Wagner, author of the guide to Caterpillars of Eastern North America, Dr. Felix Sperling of the University of Alberta and Dr. Bruce Walsh, of the University of Arizona, co-wrote in a 2010 article in the News of the Lepidopterist’s Society.

Again, this seems like a case where federal regulation will do more harm than good since the children that most benefit from the tactile experience of raising butterflies are often those living in urban settings with limited access to nature.

One of the most contentious issues in the petition is a claim on page 74 that “millions” of Monarch butterflies are released into the environment by commercial butterfly breeders each year.

The claim appears greatly exaggerated to the International Butterfly Breeders Association (IBBA), which challenged the number in a press release headlined, “Number of Monarch Butterflies Released Annually Closer to 32,000 than ‘millions and millions’ as Claimed by Endangered Species Act Petitioners.”

[DISCLOSURE:  I serve on the board of the International Butterfly Breeders Association but do not raise butterflies commercially.  I also am a member of the Xerces Society and have hosted both Dr. Chip Taylor and Dr. Lincoln Brower at our ranch.]

The IBBA challenged the basis for such a claim, noting that the “millions and millions” citation was, in fact, lifted from a single newspaper op-ed piece published eight years ago.  The author, Professor Jeffrey Lockwood, University of Wyoming, acknowledged the number was guesswork.

“That such an unverified claim surfaced in a formal petition before the Secretary of the Interior demonstrates a serious failure in documentation at best,” Kathy Marshburn, IBBA president, said in the press release.

Dr. Tracy Villareal, an IBBA board member, oceanographer, and part owner of Big Tree Butterflies butterfly farm in Rockport, Texas, called the claim “misleading and poor scholarship.” Villareal told me by phone that he would grade such secondhand references unacceptable in a graduate student’s dissertation.

“The authors made no attempt to determine the composition of the 11 million–how many of each species, for example. Nor did they attempt to contact the author to determine how he arrived at this number.  It took me about four hours from my initial email to Professor Lockwood to find out how it was done.”  Read the IBBA’s challenge to the numbers for yourself.

OE Spores with Monarch Butterfly Scales

OE spores can be debilitating for Monarch butterflies.   Concerns about infecting the wild population with the nasty spore persist, and studies continue.  Photo courtesy of MLMP

The petitioners believe that commercial breeders release diseased butterflies into the wild population, potentially damaging it. In particular, the unpronounceable Monarch-centric spore, Ophyrocystis elektroscirrha (OE), poses special concern since it debilitates the butterflies and appears to thrive in conditions where the creatures congregate en masse, are crowded, and/or where milkweeds overwinter, carrying the spores into the next season.

Yet, scientists agree that OE is present in the wild population, too, just as Streptococcus, the nasty sore throat-causing bacteria, is present in the human population. Only when health or conditions are degraded does the disease overtake the butterflies. The science is still uncertain on this.  Studies continue.

Like any industry, commercial butterfly breeding attracts good citizens and bad, but it seems highly unlikely that people who gravitated to the challenging task of breeding butterflies for a living would intentionally release damaged goods into nature. That just makes for bad business. Does the industry need better checks and balances on the health of livestock released into nature?  Absolutely.

The IBBA, an international organization of 104 breeders, plans to release new counts for the number of butterflies released annually at its conference that begins November 12 in Ft. Lauderdale. The organization also will host a discussion on changing or increasing self-policing practices of its membership to keep livestock as disease-free as possible.  As Villareal said in a recent email exchange on the DPLEX list, a listserv frequented by hundreds of folks in the Monarch community, “Working from clean breeders is a critical first step in production. I repeat this for everybody in the back row. CLEAN BREEDERS ARE CRITICAL.”

The ESA petition has created conflict in the small-but-passionate world of butterfly advocates.  A far better use of the community’s time and energy could be spent on initiatives and public education campaigns to restore migratory habitat.

It’s already happening in many ways, through government and small-but-significant public- private partnerships.

In June, President Obama issued a presidential memorandum calling for all federal agencies to “substantially expand pollinator habitat on federal lands, and to build on federal efforts with public-private partnerships.”  Pollinator Week Proclamations have been declared in 45 states, recognizing the vital services that pollinators provide.  The EPA released guidance to help scientists assess the potential risks various pesticides pose to bees, and the USDA announced an $8 million initiative to provide funding to farmers and ranchers who establish new pollinator habitats on agricultural lands as part of its Conservation Reserve Program.

Here in my hometown, we are working with the leadership of San Antonio’s Hemisfair Area Redevelopment Corporation to include pollinator habitat in their upcoming reimagination of the historic 65-acre downtown park that was home to the city’s 1968 world’s fair. Our local public utility, CPS Energy, recently supported the installation of a pollinator garden right downtown at their headquarters on the San Antonio River Walk.   And on our city’s heavily developed northwest quadrant, Hardberger Park has a dedicated butterfly garden. The park conservancy is raising money for a spectacular land bridge that will facilitate safe movement of pollinators and other wildlife.

Let’s focus on individual actions and crafting effective public-private partnerships that raise awareness, plant more milkweed and nectar plants and make rebounds like 2014 common fare–and keep the federal government out of our yards.

Migrating Monarch Butterflies Stymied by Wind, Storms in Texas Hill Country

Hundreds, perhaps thousands, of Monarch butterflies clustered along the Llano River this weekend, clinging to pecan tree branches as strong winds from the south kept them in place, temporarily halting their journey south toward Mexico and making easy work for Monarch taggers.

On Friday, winds shifted temporarily, blowing out of the north.  Temperatures dropped  40 degrees–from 93 to 53. The shift blew in a fresh crop of the migrating creatures.  Then early Saturday morning a dramatic thunderstorm dumped 1 – 4 inches of rain in the Texas Hill Country, knocking out electrical power and bringing heavy cloud cover that kept the butterflies once again in place for the day.

“Last night was great,” Jenny Singleton texted regarding Friday night. Singleton, our friend and fellow Monarch butterfly enthusiast, first introduced me to Monarch butterflies back in 2006 when she invited me to her Texas Hill Country ranch to “tag some Monarch butterflies” along with a group of her friends and family.

The tradition continues today during peak migration each year.  I’ve borrowed the practice as well, inviting friends and family to celebrate my October 13 birthday at the ranch, tagging butterflies along the Llano.  I’m lucky my birthday falls right in the middle of peak migration season, which this year runs October 10-22 for our latitude.

“Nothing tonight,” Singleton texted on Saturday. “Why? Too cold?” she asked, echoing my own thoughts about schizophrenic weather conditions.

As the sun returned on Sunday, Monarchs started moving again, clustering into groups of 20 -50 and making for a fantastic day of tagging.

The butterflies bunched up to stay warm and protect themselves from the wind, occasionally busting off the trees when the sun was just right, floating and flitting in the gorgeous autumn day. The pattern made for full nets, sometimes swooping 20 in one swing.  See the video above and you’ll get the idea.

Our team from Austin and San Antonio recorded more than 300 of the stymied migrants as peak migration kicked into gear right on schedule for the Texas Funnel. Singleton tagged 271 over four days this weekend, compared to 333 last year, and categorized the weekend as “disappointing.” Keep in mind this is a woman who has tagged more than 1,000 butterflies in a single weekend. “Crazy weather” was to blame for what she considered low tagging numbers in Hext, Texas, just 30 miles away from our stretch of river.

What a handful! Winds out of the South made for fantastic tagging last weekend, keeping Monarch butterfly clusters temporarily in place. Photo by Monika Maeckle

With big winds out of the south followed by thunderstorms, cold temps and then a blast from the north, conditions made for “Perfect migrating, not great for tagging,” said Singleton.

The story was different for us.   Monarchs hugged the trees, protected by a limestone escarpment and a linear grove of pecans, making for easy–and often loaded–net swoops.  All in all, a “Monarch-u-mental” weekend of butterfly fun, and a hopeful sign for a Monarch butterfly rebound. We’ll be back for more on Friday.

Monarch Migration Update: Lone “Cat” on Llano, Butterfly Cloud Spotted on Radar

No woman is an island, but this caterpillar had his own—right in the middle of the Llano River.

A quick kayak tour on Friday revealed another first in my eight years of tagging and monitoring Monarch butterflies: a fifth instar Monarch butterfly caterpillar clinging to a single milkweed stalk in the middle of the Llano.

This slideshow requires JavaScript.

I had noticed this milkweed plant a week ago. How inspiring that a single, solitary Asclepias incarnata seed found its way to the silt surrounding one of the many limestone bedded “Chigger Islands” that dot our stretch of river.  A result of seed balls thrown last Fall?  Maybe–or Mother Nature’s grand plan.

It laid down roots, put out stalks, chutes and flowers, and attracted at least one female Monarch butterfly to grace its leaves with eggs. I recall gathering at least one egg from here on September 14.

But obviously I missed this guy–or was his egg laid later? Maybe he had just hatched and tucked himself into the petals of the pink flowers when I examined the plant last week.  In any case, eight days later, he’s ready to bust his stripes and go chrysalis at any moment. After two days of more milkweed in the well-fed, safe confines of a yogurt container-turned caterpillar cage in San Antonio, he formed a chrysalis. In another seven – 10 days, he’ll hatch and we’ll tag and release this Monarch so he/she can join the migration and head to Mexico.

The migration continues, with reports from Ontario and points south suggesting the rebound we hoped for will arrive in about two weeks. The latest report from Journey North has Monarchs skipping down the Atlantic coast.

“The Atlantic Ocean is directing the migration now in the east,” wrote Journey North founder Elizabeth Howard in her report September 25.  “Monarchs hug the coast as they travel southward, trying to avoid the winds that can carry them out to sea.”

Dr. Chip Taylor, founder of Monarch Watch relayed to the DPLEX list, an old style list-serv that reaches hundreds of butterfly enthusiasts, academics and citizen scientists, that the peak had hit Lawrence, Kansas, where the Monarch Watch citizen scientist program is based.

“The numbers seen are certainly greater than observed during the last two migrations,” wrote Dr. Taylor, referencing good numbers of Monarchs for September 25-28 in Lawrence.  “This is another late migration,” he added.

“The leading edge of the migration usually reaches here between the 9-11th of September with an estimated peak on the 23rd. It’s hard to say but, it’s probable that the peak occurred yesterday – the 27th,”  he said.

In contrast, the Associated Press reported the first migrating Monarch butterflies arrived in the northern border state of Coahuila, earlier than usual.   The report characterized the early arrivals as “a tentative sign of hope” for the migration, given the historic drop in their numbers last year.

Bee on Frostweed

Luis Fueyo, head of Mexico’s nature reserves, told the reporter that the first butterflies have been seen entering Mexico earlier than usual. “…This premature presence could be the prelude to an increase in the migration,” he was quoted as saying. Usually the first arrivals don’t get to Mexico until October.

Here in the “Texas Funnel,” we saw a handful of Monarchs flying in the Texas Hill Country this weekend. Most appeared to be laying eggs and did not exhibit directional flight. Frostweed was the big draw, not only for Monarchs but other pollinators, especially bees.

Butterfly cloud in St. Louis

In other news, a strange cloud spotted via radar above the city of St. Louis last week by the National Weather Service was identified as a Monarch butterfly mass, making its migratory trek south. “Sometimes our radars pick up more than precipitation,” the Facebook post read, provoking a social media flutter. The “butterfly cloud” even looked obtusely to be in the shape of a butterfly—well, if you used your imagination.

Migration Update: It Takes a Village to Feed Hungry Monarch Butterfly Caterpillars

It takes a village to keep the Monarch butterfly migration going.

Last week I discovered dozens of Monarch butterfly eggs at the ranch when a cold front pushed a vanguard pulse of migrants down to the Texas funnel.   The early moving butterflies broke their reproductive diapause to lay hundreds of eggs.  I collected more than 70 from Swamp milkweed, Asclepias incarnata, along the banks of the Llano River and dozens more from our downtown San Antonio garden.

That’s the good news.

The problem:  where would we get enough “clean” milkweed this late in the season to feed the hungry critters, who eat more than 2,000 times their birth weight in milkweed leaves?  NOTE:  “clean” milkweed is plant material that has never been sprayed with systemic pesticides, which routinely kill the caterpillars.

I’ve written before about the scarcity of chemical free milkweed, especially this time of year.  In fact, we are exploring the idea of becoming a native, chemical free milkweed supplier.   Please take our poll and let us know if you would support such an endeavor.

San Antonio nurseries all told similar stories: “Sorry, we’re out,” or “Yes, we have some, but can’t guaranteed that it’s never been sprayed.”

One nursery had milkweed, but couldn’t guarantee it had not been sprayed by the grower with systemic pesticides, which can linger in the leaves for months.   And we all know how that turns out–just read one of our most read posts of all time, Desperately Seeking Milkweed, details the sorry stories of two friends who served pesticide laced milkweed to their hungry cats.

Boo-hoo! Dead Monarch caterpillars fall victim to pesticide laced milkweed

What to do?

Turn to the community, of course. In the case of Monarchs, that’s a broad collection of friends, family and acquaintances near and far. One of our favorite Austin nurseries, The Great Outdoors, almost always has a supply of chemical free milkweed on hand. A quick call to the native plant destination confirmed they had about a dozen large pots of clean, Tropical milkweed, Asclepias curassavica, left over from a spring shipment.  The plants could provide the massive foraging and feasting buffet required to take our dozens of ravenous crawlers to the butterfly stage of their life cycle.

But drive 150 miles roundtrip to Austin from San Antonio on the clogged IH-35 on a busy Saturday to collect plants? Sigh.  NOT very appealing.

IMG_1840

Good thing my dear friend Teresa Elliott lives a few blocks from Great Outdoors and volunteered to pick up a few plants for me at $15.95 a pop.  (Yeah, kind of expensive–but worth it.)  Teresa wouldn’t even let me reimburse her. “I’m doing it for the cause,” she said.

Meanwhile, another good friend and Monarch tagging pal, Tracy Idell Hamilton, agreed to pick up the bushy bloomers since she was already in Austin attending the Texas Tribune Festival. Teresa’s house happened to be just a few blocks away from where Tracy was staying.

IMG_1839

Such collaboration is commonplace in the sphere of the Monarch butterfly migration, where volunteers, citizen scientists, professional academics and entomologists routinely share data, tricks of the trade, and information to keep the migration going.  It’s the nature of the passion.

Upon arriving home from a day of errands last Saturday, three “ginormous” milkweed plants waited at my door.   The plants were mature, relatively aphid-free, and ready to be attacked by my hungry cats.

Hungry caterpillars

More, please! These hungry caterpillars outgrew their container and were ready for a bushy milkweed buffet. Photo by Monika Maeckle

The gang had been chomping happily on milkweed from my downtown garden, but even if we used every plant in the yard, it wouldn’t be enough to sustain them.   For the first few days, my mom, Hilde Maeckle, would help me daily clean out the caterpillars temporary plastic container home of frass, or caterpillar poop, which can be monumental. We would wipe down the container, lay out fresh leaves for them, and leave them to munch.

But now they were getting too big and too crowded, so it was time to transfer them to the plants–which arrived just in time.

Tropical milkweed

The caterpillars are now munching happily on these milkweeds, growing before our eyes.  In a day or so we’ll transfer the plants with the caterpillars to a large netted cage, or “caterpillar condo” to keep them from wandering off.  Eventually, each caterpillar will seek a quiet place, form an upside down “J” shape, then morph into a beautiful jade green chrysalis to hatch sometime during the second week in October, just as peak migration hits San Antonio.  We look forward tagging and sending them on their way.

Thanks to all the friends, family, professional and citizen scientists near and far who  work hard to sustain the seasonal miracle of the Monarch butterfly migration.

Migration Update: Monarch Butterfly EGGstravaganza on the Llano River

We’re hearing positive reports from further north about the Monarch butterfly migration. Masses of Monarchs look to be in the Midwest right now, according to dispatches from the DPLEX list, the Monarch butterfly listserv that reaches hundreds of butterfly enthusiasts, citizen scientists, academics and others.

“It was obvious that the crest of the migration was passing through Omaha today,” Dr. Ted Burke, an entomologist and behavioral biologist at Creighton University wrote on Sunday. Dr. Chip Taylor, founder of Monarch Watch, clarified that the ”crest” is actually the “leading edge” of the migration which should be followed by the peak six – eight days later.

“The numbers observed were incredible….At one prairie I counted 79…At the other prairie, I counted 150!” Burke wrote, adding that last year the numbers at the same locations were eight and twelve, respectively.

Monarch butterfly eggs

Musta been a wild weekend on the Llano River in the Texas Hill Country: 77 eggs gathered from Swamp milkweed. Photo by Monika Maeckle

About 850 miles south of Omaha, a dramatic cold front that began in Canada pushed 20-mile winds out of the north and dropped temperatures from the 90s to the 50s. The front blew some early migrants into the “Texas Funnel” along the Llano River this weekend. Judging from the dozens of eggs observed and collected on Sunday, it must have been a wild Saturday night in the Texas Hill Country.

Early migrants broke their reproductive diapause to drop their small yellow pearls on the undersides of Swamp milkweed, Asclepias incarnata, leaves.   In my eight years of tagging and monitoring, I have never seen so many eggs.   I stopped gathering after 77, wondering where I would find enough milkweed to feed the resulting hungry caterpillars.  Note to my San Antonio area friends:  you’ll be hearing from me regarding milkweed loans.

Another first: I found a fully formed Monarch chrysalis dangling from milkweed leaves over the river.

Two caterpillars and about half a dozen adult Monarchs also made an appearance, presenting the entire life cycle in a two-hour kayaking tour. With tags in the boat, I only took one swing with my net all afternoon.  I missed.  She was probably an egg-laying female anyway, so unlikely to migrate. See our recent story on the premigration migration.

Our friend Veronica Prida reported a FOS (First of Season) migrant Monarch in her front yard in Alamo Heights on Saturday.   The faded female nectared on dramatic Pride of Barbados while Veronica snapped photos.  Upon returning Monday, we also had a female laying eggs in our downtown garden on Swamp milked transplanted from the Llano.

Monarch on Pride of Barbados

All this bodes well for the migration. The 77 harvested eggs will take about one month to become butterflies, hatching just in time for peak migration in our latitude, October 10 – 22. They’ll be tagged, released and join the migration.  We promise to fatten them up with ample nectar from our gardens, sending them on to Michoacán with massive healthy fat deposits to see them through the winter.

Ideal conditions prevail here with Goldenrod, Frostweed, Swamp Milkweed and other fall flowers still in bloom, and almost tropical weather in place.  Meteorologists predict a “mild El Nińo” pattern this fall, translating to more rain.  How sweetly ironic and preferable to last year’s dreary reports of drought and decline.

How to Track the Monarch Butterfly Migration from your Desk

Monika,
….I would love to see the migration at the Llano River. We have a 5th wheel [travel trailer] and have camped at the KOA on the Llano River in Junction, Texas….

Is this the area where we would be able to see the migration? I think I saw the estimated dates for peak migration at the Llano River is Oct 10-27, 2014. Is this correct? Want to make sure I am in the right place and right time if possible.

Thanks for the information and for your newsletter/emails about the butterflies. Just love them.

                                     Sincerely,   Elaine

Emails like the one above are common this time of year.  Many of us who follow Monarchs  try to stay on top of the migration to plan tagging outings and sate our extreme interest and curiosity.

Tagged Monarch butterfly

Won’t be long and Monarch butterflies will be passing throughout the Texas Funnel.  Check out the online tools that will help you track the migration.  Photo by Monika Maeckle

I check the Monarch Watch peak migration calendar, monitor the wind and weather, and keep an eye on email lists and social media before inviting my butterfly loving friends to join me for a weekend of tagging on the Llano River. Lucky for me my birthday is October 13, which generally falls in the middle of prime migration time (this year, October 10 – 22 for our latitude).  That all makes for a great Monika’s Monarch birthday weekend.

In the meantime, it’s fun to catch vanguard migrants on their early journeys south for observation and tagging.   And for those with limited outdoor access, social media and the web provide chances to experience the migration virtually. (Yeah, not the same, but better than nothing.)

Elaine, no sure way exists to predict exactly which weekend Monarchs will mass along the Llano River near Junction.   But by tapping the resources below, you’ll be able to determine the best chance of seeing the most Monarchs.

So make note and check out the cool tools available at the intersection of technology and (citizen) science.

Journey North

First stop should be the Journey North website.  A free internet-based program that explores the interrelated aspects of seasonal change, Journey North tracks wildlife migrations including hummingbirds, whales and bald eagles.   This time of year, the Monarch migration gets top billing.  Journey North founder Elizabeth Howard told us that 400,000 people per month visit the site during Monarch migration season.

And with good reason.  Journey North offers constantly updated maps showing where adult Monarchs, eggs, caterpillars, and roosts have been spotted.  Photos and reports from citizen scientists, butterfly enthusiasts, professional photographers and academics populate the site, along with training and resources for teachers and others.

In last week’s map, below, recently observed overnight roosts were limited to Wisconsin and Minnesota.  Note to Elaine: you won’t be missing anything in Junction, Texas, for a while.

Journey North also posts a weekly report on Thursdays based on observations from Monarch butterfly enthusiasts of all ages, from Canada to Mexico.

Journey North founder Elizabeth Howard often writes the updates herself, like this one from last Thursday.  “The largest counts have been in nectar-rich hotspots with Liatris. This late-blooming plant is a monarch magnet! When planting for monarchs, flower bloom-times are important. Include late-bloomers to attract migrating monarchs and provide vital fuel for migration.”

 Twitter

Using Twitter as a search engine is another great Monarch butterfly tracking tool. It provides real-time updates of Monarch butterfly sightings and offers a timely feed on Monarch butterfly news, from many of my favorite sources–including Journey North and Monarch Watch.

Granted, not everyone uses Twitter, but an estimated 270+ million people and myriad organizations tap the free, real-time application as a search engine and personal or professional broadcast outlet.

That means you can visit http://search.twitter.com and punch in “monarch butterflies” or “monarch migration” or “tagged monarch butterfly” and dozens of hours-old “tweets”–brief 140-character updates—will be returned, telling you where Monarchs are flying RIGHT NOW.

Such a search today turned up this tweet from Minnesota State Representative for District 60B, Phyllis Kahn: “Monarch butterfly tagged and released. About to take off for Mexico.”   Kahn offered the lovely Monarch on Goldenrod pictured above with her tweet.

Twitter search ONLY indexes recent updates. Google and other search engines are more akin to archives for the entire web. You can try searching Google News, but this won’t return the real-time reports Twitter delivers.  Check it out.

Wind Map

For those of us who live in the Texas funnel, the wind plays an especially significant role in planning for Monarch tagging outings. I work full-time, so during Monarch season, I plot each weekend for maximum Monarch activity.

Before leaving town, I check the Wind Map, a fantastic tool that shows which way the winds are blowing.  If winds are coming out of the North, that means Monarchs will be riding the wave and we could have a big mass when they drop from the sky at sunset and roost for the night.

If winds are coming from the South, Monarchs won’t be moving much. That could mean they’re stranded in place, which could also make for good tagging since they will likely hang out and nectar on late blooming flowers.

Screen Shot 2014-09-07 at 6.13.58 PM

Dr. Chip Taylor, founder of Monarch Watch, recently suggested that tracking wind patterns through the wind map and matching them up with tagged Monarch butterfly recoveries would be a great citizen scientist project.    We’ll have to see if someone tackles that.

Either way, the map lets us know what’s coming.  Plus, it’s simply a dreamy tool, with it’s  visual articulation of nature’s breath expressed in real-time.

As the site descriptor says: “An invisible, ancient source of energy surrounds us—energy that powered the first explorations of the world, and that may be a key to the future. This map shows you the delicate tracery of wind flowing over the US.”

The talented team are committed to a “rigorous understanding of visualization” informed by their Ph.Ds–Viégas’ graduate degree from the MIT Media Lab; Wattenberg’s in mathematics, from U.C. Berkeley.

LOVE this project.

Monarch Watch Facebook Page

If you’re reading this and you’re on Facebook, then you likely have already “LIKED” the Monarch Watch Facebook page.  If not, go ahead, do it now, and join the party.  (And while you’re at it, why not LIKE the Texas Butterfly Ranch Facebook page?)

With more than 23,000 fans, Monarch Watch’s page serves as a delightful online plaza where the Monarch Watch team from the University of Kansas engages with the rest of us to share information, photos, and wax passionate about Monarch butterflies and their migration.   Citizen scientists, recreational observers, and professional and amateur biologists and entomologists join the conversation.  Like this:

Screen Shot 2014-09-07 at 2.29.58 PM

Toby Smith, who posted the above photo, is from Garland, Texas.  That’s just 292 miles north of here, so that tells me at least individual Monarchs are en route.  Be sure to click on the “posts to page” tab so you can see what people in the field are seeing.

Journey North devotes itself to wildlife migrations besides Monarch butterflies, but the Monarch Watch website brags Monarch butterflies, all the time.

Monarch Watch website offers Monarch info 24/7/365

Based at the University of Kansas at Lawrence, Monarch Watch founded the citizen scientist tagging program embraced by thousands of us who tag Monarchs each fall.  Its comprehensive website offers information on how to tag a Monarch, raising milkweed, rearing Monarch caterpillars, and a database of all the Monarch tags recovered in Mexico, so those of us who tag can find out if any of our butterflies made it home.

The site also posts predictions for when the peak migration will occur at your latitude based on Monarch Watch scientists’ well-researched opinions.  The Monarch Watch blog is also worth a look and you can join 30,000 others to get on the mailing list.

D-Plex List

If the above won’t sate your migration curiosity, then consider signing up for the D-PLEX list,  an email exchange that includes about 650 scientists, conservationists, enthusiasts, and others, including some very interesting characters.

Named after the Monarch butterfly’s Latin designation, Danaus plexipus, the D-PLEX is an old fashioned email listserv started by Monarch Watch founder Dr. Chip Taylor and invites the public.  Sign up to receive D-PLEX emails on the Monarch Watch webpage.

Careful, though.  The D-PLEX can overtake your email inbox.   Conversations can escalate, generating dozens of emails a day, many of which you may not find useful.   I’ve set up all D-PLEX emails to forward to a special email box that I check once a day, so as not to be overwhelmed.

Don’t forget to check in with us here at the Texas Butterfly Ranch, too.  We’ll do our best to keep you posted.
