Mega Grower Color Spot Nursery to Consider Growing Clean, Chemical-free Milkweed

Color Spot Nursery, one of the top national wholesale growers in the country, said this week they will explore heeding the call for clean, chemical-free, preferably native milkweed plants.   The company said they are considering growing select Asclepias species, the only plant on which Monarch butterflies will lay their eggs, WITHOUT any systemic pesticides.  Thanks to Craig the Butterflyman for the tip.

The California-based mega grower, which has seven nursery locations in Texas including one in San Antonio, said they were responding to their customers, which include Lowes, Home Depot, Wal-Mart and hundreds of independent nurseries across the country. Color Spot does not sell directly to the public.

“Our customers got in trouble with the community,” said Kevin Grossberndt, Commercial Sales Manager for the Southwest Division of Color Spot.   “We all learned a lesson.”

Gorssberndt said Color Spot is well aware of Monarch butterfly enthusiasts’ dismay at buying milkweeds to feed hungry Monarch caterpillars, and being misinformed by retail nursery staff that milkweed plants had not been sprayed with systemic pesticides.

After customers purchased milkweed plants from local nurseries and later placed their caterpillars on them to feed on the milkweed leaves, the caterpillars perished within hours.   That’s because large growers like Color Spot often spray the plants with systemic pesticides early in the year and the poisons used can linger for many months.  The phenomenon has been well documented on these webpages.  We call it Desperately Seeking Milkweed syndrome.

Bernhardt, trained as a horticulturist, said Color Spot is considering which species to plant and is likely to go with Tropical milkweed, Asclepias curassavica, and Butterfly weed, Aslcepias tuberosa.

The Texas Butterfly Ranch and our hydroponic milkweed growing partner Local Sprout made a pitch to Bernhardt to consider cultivating Swamp milkweed, Asclepias incarnata, since it is relatively easy-to-grow, a great nectar and host plant and prolific pink bloomer native to the area.  Most native Texas milkweed species are famously persnickety to grow. Swamp milkweed is not.  Check out the Texas Butterfly Ranch milkweed guide for more info.

Dr. Chip Taylor, the founder of Monarch Watch, chimed in via email, suggesting that Color Spot might try Green Antelope Horn milkweed, Asclepias viridis.  “Viridis is probably the second most important plant on the Monarch’s menu,” Dr. Taylor said.  “It’s the main host for first generation Monarchs. It’s also the most abundant of the Texas milkweeds and survives in pastures quite well.”

Which is absolutely true, but it’s famously challenging to grow from pots and transplants.

“Texas is too dry and hot for syriaca,” Taylor added.

During a tour of Color Spot’s 400-acre growing facility in western San Antonio near Lackland Airforce base, Grossberndt described the special challenges commercial growers will face in growing chemical-free milkweed.

As we all know, milkweed is an aphid magnet, and many people will not buy plants with aphids on them.   Traditionally, Color Spot deals with aphids and other pests via pesticides in order to deliver pristine plants to retail outlets.

With labor one of their highest costs, hand removal of aphids may not be practical.    Color Spot already uses robots to move plants around.   The R2D2-like machines rearranged a plot of potted rose bushes as we all watched in amazement.  But since its doubtful that an aphid-squishing robot will be developed anytime soon, Color Spot will have to be resourceful.

“We might be able to do it with a soap knock-down or possibly explore using beneficials like ladybugs or parasitoid wasps,” said Grossberndt. “We’ll have to see.”

Dr. Taylor also recommended beneficial insects.  “We are happy to recommend various biological control agents. They seem pricey until you see how effective they are but the grower has to have personnel that is alert to the build-up of pests so that the biologicals can be deployed effectively,” he said.    Grossberndt agreed that training of personnel, especially Color Spot’s technology services team, would have to be part of the plan.

Since the nursery typically sprays ornamental and other inventory with systemic pesticides, the growhouse would also need to be strategically placed out of any possible wind drift and would require polyurethane sides, versus less expensive shade cloth or plastic to assure no chemicals entered the clean zone.

Grossberndt showed us one quanset hut filled with a mix of Tropical milkweed and Butterfly weed–some newly sprouted from seed this year, others cut back and sprouting new growth from last season.   Aphids adorned the underside of the older plants, suggesting the plants had not been sprayed with pesticides.

Yet.

Will they be?  “I’m hoping they won’t,” said Bernhardt.  “These plants were in the middle of other plants, so we’ll just have to see how it goes,” said Bernhardt.  “I’m making the case.”

Grossberndt suggested that Color Spot might have some clean plants on the market by late summer or early fall–hopefully in time for the fall migration when those of us who raise Monarchs often run out of milkweed for those butterflies that break their diapause and reproduce here.  ” I can’t really guarantee a timeline,” said Grossberndt.

P.S. Have you taken our What Kind of Milkweed Survey?   Help us convince Color Spot and other commercial growers to offer clean, chemical free milkweed by voting for the species you’d like to see in local nurseries.  Here’s the link and feel free to share the survey.  GRACIAS!

Q & A: Dr. Lincoln Brower talks Ethics, Endangered Species, Milkweed and Monarchs

At 83, Dr. Lincoln P. Brower has studied Monarch butterflies longer than anyone on the planet. He first became enamored of butterflies as a five-year-old in New Jersey and later

Dr. Lincoln Brower–photo via Monarch Butterfly Fund

by Monarchs when he learned they don’t taste good to predators. His famous  “Barfing Bluejay” photo, below, proved their unpleasant taste to predators and always gets a chuckle when I share it in presentations.

Brower followed his passion and turned his attention to Monarch biology as a grad student at Yale in 1954. He has visited the roosting sites in Mexico more than 50 times since his first trip in 1977–15 years BEFORE Dr. Chip Taylor, the other grandpa of the Monarch community, started the citizen scientist Monarch butterfly tagging program, Monarch Watch, in 1992.

So it’s no surprise that after a lifetime invested in the dramatic orange-and-black butterflies, Brower takes Monarchs personally. When he recently lent his name to the petition to list the Monarch butterfly as “threatened” under the Endangered Species Act (ESA), few people were surprised. NOTE: The period to join 306 others who have commented on the petition closes March 1, 2015.

Barfing Bluejay

Dr. Brower graced the Texas Butterfly Ranch with a visit back in October of 2011 when he toured the Texas Hill Country during the peak of the historic Texas drought.

The man is amazing. Tromping across the limestone watershed, butterfly net in hand, we tagged dozens of butterflies that day for a study he was doing.  Between net swoops, Brower taught me how to identify male from female Monarchs without having
to open up their wings, a trick I still use today.

Brower can be a purist.  He’s said that Tropical milkweed, Asclepias curassavica, should only be planted in a laboratory or controlled environment because it might spread disease in Monarchs–a directive he recently amended. Now he advises the Monarchs’ favorite host plant be planted no further north than Orlando, Florida. Brower also called the recent 70% increase in Monarch numbers “catastrophic.” “That change is trivial,” said Brower. “We were thinking it would be more than two hectares. What we need is up to five hectares.”

Since the petition was submitted, much attention has been focused on our favorite migrating insects, who’s “canary in the corn field” status makes them pollinator decline’s apt and timely poster child. Climate change, overzealous pesticide use, genetically modified crops and general human domination of the planet all play their role in challenging Monarch butterflies and the entire food web.

Awareness of these critical issues is fundamental to addressing them and the ESA petition has raised unprecedented awareness. Some of us may disagree that ESA status for Monarchs is the best tool for the job, but it’s impossible to not recognize how the petition has served to raise the profile of Monarch butterfly and pollinator decline. So thanks to Brower and the petitioners for creating needed drama.

We recently chatted with Dr. Brower, who currently serves as Distinguished Service Professor of Zoology Emeritus at the University of Florida and Research Professor of Biology at Sweet Briar College. The conversation migrated from email to phone and back. Here, in his words, is how he sees the current landscape.

Q. Recent events, including your participation in filing a petition to list the Monarch butterfly as “threatened” under the Endangered Species Act, have brought unprecedented attention to the decline of the Monarch butterfly migration.    Was this the honest intent of filing the petition–to bring attention to the situation rather than actually list it?  Or do you still believe that listing the insect as endangered is the appropriate approach to conservation?

Brower: Those involved in writing the petition had, I think, two goals:  One, to raise public and government awareness; and two, to generate funding of varied mitigation programs, private and public.

Q.  Do you still believe that listing the Monarch butterfly is the best option or have you changed your mind?

Brower: I did when I signed onto the petition and the evidence I have seen so far seems to be supporting that contention. I think we will have to wait and see what happens. It is possible that nothing we can do will preserve the Monarch’s migration and overwintering biology spectacle.

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

Citizen scientists like Catalina Trail were instrumental in pieceing together the mysteries of the Monarch butterfly migration.

Q. If the Monarch becomes listed as threatened under the Endangered Species Act and milkweed and physical contact with Monarch butterflies will likely be controlled, do you share concerns about the disenfranchisement of the citizen scientists and Monarch butterfly enthusiasts that have for decades been instrumental in unraveling the mystery of their migration?

Brower:  Appendix B page 162 of the petition is worded in confusing legalese but states that citizen scientists’ participation and conservation efforts will not be restricted. I have recommended that the stated limit of ten butterflies per person be raised to 100.

Q. Recent studies link Tropical milkweed, Asclepias curassavica, to increases of OE in Monarchs. If other species of milkweed–Swamp or Common, for example–had been the species widely cultivated and made available commercially to gardeners, would we be having the same issues with those plants?

Brower: Curassavica likely would not normally have entered Texas from Mexico in the past or future even with global warming. It does not tolerate desert conditions in its natural geographic distribution. As I have stated elsewhere, I think it is a mistake to plant it north of the City of Orlando, Florida latitude in the US.

The recent paper by Satterfiled, et al, is relevant. Propagation of locally occurring native milkweeds and planting them widely in gardens along roads, etc., is what should be done.  The Monarch community needs to jump on this bandwagon and influence plant nurseries to do this for their sales. Bring everyone together to do the best we can to increase native milkweed habitat.

Got milkweed?

Tropical milkweed is technically not native but the most widely available species of Monarch host plant. Native milkweeds are best.

Q.  Is it at all arrogant of us, the human species, to insist that the Monarch migration continue as climate change, human impacts and other factors conspire to make it possible for Monarch butterflies to continue their life cycles and reproduce without migrating 3,000 miles? And if the need to migrate changes or no longer exists, who are we to say that it should continue? (I wonder what a Monarch butterfly would say if we gave them a choice of migrating or not?)

Brower: As we discussed at length, these are ethical questions. Should we try and preserve natural phenomena such as the Monarch migration? Analogously, should we try and save pandas, polar bears, endangered plants. etc.

Turn the question around: is it ethical to let these things go extinct when we have the ability to prevent that from happening? Are people the only creatures with a right to rich and natural lives on this planet?

You know my answer, it is dead wrong not to try to prevent loss of natural species and what they do from bacteria to humans. If rabies were to take over, the view of letting it be would mean the end of dogs. How can anyone even think that is tolerable. I feel the same way about the Monarch…In addition, preserving it is symbolically important:  it is the “canary in the corn field” telling us something very broad and serious is wrong with managing our planet.

Q:  Dr. Brower, I agree with you regarding species going extinct, however we are talking about the migration.  Few folks believe the Monarch butterfly will become extinct.  Do you make a distinction that some behaviours outlive their usefulness–such as, perhaps, the Monarch migration?

Brower: My colleagues and I have referred to the Monarch migration/overwintering behavior as an endangered biological phenomenon. My thesis above also applies exactly to this category of biodiversity.

Should we work to restore the bison migrations or just keep them in a few zoos and confined pastures? What about the bamboo forests of China: let them and the panda inhabitants be destroyed while keeping a few panda breeding programs going to make sure zoos are profitable? Bioethics again.

Survey: Monarch Butterfly Enthusiasts Will Pay More for Clean, Chemical Free Milkweed

A Texas Butterfly Ranch survey conducted in late 2014 found that Monarch butterfly enthusiasts are willing to put extra money where their beloved Monarch caterpillars mouths are:  on clean, chemical-free (preferably native) milkweed.

Got clean milkweed?   Great, we’ll pay more.   Is it native?  Yes, please–even better.  Photo by Monika Maeckle

Are you listening, American nursery industry?   You can make more money if you grow milkweed without chemicals.  Make them native and you can likely charge another premium.

“Truthfully, I’ll pay anything to keep my cats safe!”

Our online poll of 363 respondents found that 96% responded “Yes” to the question:  “Would you pay more for “clean,” chemical-free milkweed that is raised organically, sustainably and locally?”

wouldyoupaymoreyesorno

The survey, which ran in various online forums from September 24 through December 31, 2014, resulted from the annual angst that arrives with each fall migration.  Late in the season, when masses of Monarchs move through town and some lay eggs on local milkweed plants, those who hope to raise the caterpillars to the butterfly stage bring them inside for “fostering.” It’s not uncommon so late in the year for people to run out of milkweed for their hungry caterpillars.

This typically sends folks running to their local nursery to buy fresh host plant–most often Tropical milkweed, Asclepias curassavica, since that’s all that’s commercially available.  Typically, when asked the provenance of the milkweed, nursery staff tell milkweed buyers the plants have NOT been sprayed with pesticides.

“When my caterpillars are down to stems, I’m just happy to be able to get ‘clean and safe’ milkweed at almost any price….They will starve otherwise! I’ve bought ‘bad’ milkweed and lost thirty or more caterpillars… it was horrible.”

Yet, upon moving their Monarch larvae to the milkweed plants, the caterpillars perish within hours.   That’s because many commercial growers use systemic pesticides to keep the plants aphid-free before selling them to our local nurseries.  Often the local nursery staff is unaware that these pesticides have been sprayed on the plants.  Nor do they seem to know that the chemicals  remain active for months.

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

The syndrome has been dubbed by those of us who follow it Desperately Seeking Milkweed and has been well documented on this website as well as referenced in comments (some of which you’ll find throughout this post) in our recent milkweed survey.

So how much, exactly, are Monarch caterpillar foster parents willing to pay for clean, chemical free milkweed?

“I grow my own plants but when I run out of food I have to run to a garden center…I always ask, ‘have these plants been sprayed with insecticide?’ and the answer is always ‘No, ma’am.’ I buy the plants and my cats die when they eat it…very sad so I would definitely pay more to keep my babies alive!  :-)

howmuchmore

About 48% said “it would depend” on the time of year and how badly they wanted/needed the plant.  Another 21% of respondents said they would pay $5 more, 5.5% said $4 more would be their limit, 10.5% said they would pay $3 more and 16.5% said they would pay $2 more.

The geographic diversity of the respondents played out like this:
Where do you live?Missing from the survey was a question asking whether or not buyers of milkweed prefer that NATIVE species in addition to chemical free and clean.  My bad.  Of the 183 comments, many expressed a desire for NATIVES.  Here’s a sampling of comments:

“NATIVE, clean milkweed please.”

“Prefer the non-tropical, if possible… Native Texas milkweed would be preferred.”

“Is there any place to buy native milkweed plants?”

“Native milkweed is hard to find in the nursery trade. I’m  rich, but I would pay a fair price.”

“What about native milkweed?”

The survey launched about a month after an August 26  petition to list the Monarch butterfly as “threatened” under the Endangered Species Act made its way to the Department of the Interior. That petition is under a 12-month review and has provoked many discussions about the gross loss of native milkweeds in our landscape in addition to a lack of available native milkweeds in commercial nurseries.

Since, interest in native milkweeds has ballooned, bringing much needed attention to Monarch butterfly native habitat restoration in our fields, landscapes, gardens–even in our caterpillar nurseries in the late fall during the migration as well as in the spring.

So listen up, commercial growers.   Native milkweeds are in high demand and short supply.  A business opportunity awaits those who pounce.   The Texas Butterfly Ranch is exploring such a venture with our hydroponic partner, Local Sprout. Stay tuned for details.

Monsanto: “We are absolutely committed” to Monarch butterfly conservation

Almost a year has passed since Monsanto Corporation stated in its Beyond the Rows blog that it was “eager” to restore Monarch butterfly habitat along the iconic creature’s migratory path.

When it comes to Monarch butterflies, Monsanto is often the villain of choice.  But the company says they are committed to helping save the butterflies' migration.

When it comes to Monarch butterflies, Monsanto is often the villain of choice. But the company says they are committed to helping save the butterflies’ migration.

That blogpost appeared in the wake of an historic meeting of the NAFTA presidents last year, when Presidents Obama and Enrique Peńa Nieto, along with Prime Minister Stephen Harper of Canada gathered 75 miles from the Monarch butterfly’s ancestral roosting sites and committed to form a task force to “ensure the conservation of the Monarch butterfly.”

On February 24, 2014, Monsanto’s blogpost, generically labeled “The Monarch Butterfly” posed the question:  What can we do to help?

“We’re talking with scientists about what might be done to help the Monarchs rebound,” the unsigned post stated. “And we’re eager to join efforts to help rebuild Monarch habitat along the migration path by joining with conservationists, agronomists, weed scientists, crop associations and farmers to look at ways to increase milkweed populations on the agricultural landscape.”

In April, First Lady Michelle Obama planted milkweed on the White House grounds, thus creating the first-ever pollinator garden at 1600 Pennsylvania Avenue. Then in August, debate ensued over whether the Department of the Interior should list the Monarch butterflies as “threatened” under the Endangered Species Act.

Monsanto, often vilified for its genetically modified corn and soybean seeds that have wreaked havoc on milkweed all along the insects’ primary breeding grounds from Canada south to Mexico, has remained relatively mum on the subject. They returned to the subject of Monarchs in a September 12, 2014 post headlined, “Helping Protect the Monarch Butterfly.” Here’s an excerpt:

“At Monsanto, we’re committed to doing our part to protect these amazing butterflies. That’s why we are collaborating with experts from universities, nonprofits, and government agencies to help the Monarch by restoring their habitat in Crop Reserve Program land, on-farm buffer strips, roadsides, utility rights-of way and government-owned land.”

So what, exactly, has Monsanto done for Monarch butterflies in the last year?

ERic Sachs, Monsanto

The Monarch community wondered exactly that this week on listservs, social media and via private emails.

As the news conference announcing the size of the overwintering population at the roosting sites in Mexico was postponed for the third time, efforts to restore milkweed by gardeners was taken to task by mainstream media, and comments on the Federal Register debating the insect’s ESA listing grew to more than 260, postings, conspiracy theories, impatience and indignation abounded.

Dr. Chip Taylor, founder of Monarch Watch, has consulted with Monsanto on the topic. He sent an email Monday to the DPLEX list, which is read by hundreds of butterfly enthusiasts, with the subject line: “Take a deep breath – exhale slowly – relax – please.”

Eric Sachs, the top Science and Policy official for Monsanto, said the multinational corporation is serious about helping Monarchs. While the NYSE-listed chemical and biotech powerhouse has publicly stated it does not support listing the insect under the Endangered Species Act because it wouldn’t “do anything to help solve the problem,” Sachs noted in an email and later by phone that Monsanto has been working diligently with public and private sector partners to “enable greater numbers of farmers to integrate Monarch habitat into existing conservation, land management and habitat expansion efforts.”

A presentation Sachs made in November 2014 to the North American Entomological Society emphasized the company’s penchant for P3s–public-private partnerships.  Tools in the conservation arsenal, according to Sachs, include grants, incentives and collaborative projects to increase habitat.

Ed Sachs Monsanto presentation

Can habitat and agriculture coexist? Good question. Eric Sachs made this presentation to the North American Entomological Society in November 2014.

Monsanto is prepared to make financial contributions to habitat preservation, Sachs said, but he did not say how much or exactly when, because the company is still trying to gain consensus from the coalition of scientists, conservationists and others tapped via the Keystone Center in Colorado.  “Obviously that plan needs to be supported with funds, which will come from Monsanto and other organizations,” said Sachs.

Dr. Taylor seconded the motion in his email to the DPLEX list, encouraging patience and a positive attitude.  “It costs $100-1000 per acre to restore milkweed/Monarch habitats, depending on the situation (and maintenance), and we are talking about restoration of a least a million acres a year just to offset annual habitat losses,” Taylor wrote. “Getting the Monarch numbers back to where they need to be will require the restoration of many more millions of acres. The investment will be significant. Partnerships are in the process of forming. Whether significant funding will be forthcoming is still an open question. Please be patient.”

Sachs said Monsanto is being “very deliberate” in developing their plan. “We want to make sure it’s robust, and measure the performance. Then we will essentially fund the program to make sure we get the bang for the buck,” he said.

How it all plays out remains to be seen. “We are absolutely committed,” said Sachs. “At the right time, people will shake their heads and say ‘this is good.’ But we’re not there yet.”

Monarch Butterfly Inches Toward “Threatened” Status under Endangered Species Act

The U.S. Fish and Wildlife Service (USFWS) announced this week it will conduct a status review to determine whether or not the Monarch butterfly should be listed as “threatened” under the Endangered Species Act (ESA).  The conservation arm of the U.S. government has been considering the matter ever since the Xerces Society, Center for Food Safety, Center for Biological Diversity and Dr. Lincoln Brower submitted this petition to the Secretary of the Interior on August 26.  Read the press release.

The petition caused quite a flutter in the Monarch butterfly community over the past few months.   Listservs and social media outlets mulled the possibilities inherent in a threatened status listing.   Hundreds of scientists and enthusiasts signed letters and petitions of support, yet others took issue with the 159-page petition.

Professional butterfly breeders and some citizen scientists (including yours truly) expressed concerns about the petition’s final sentence, which described how people like me and you will only be allowed to raise 10 or fewer Monarchs per year–unless that activity is “overseen by a scientist, conservation organization, or other entity dedicated to the conservation of the species.”

Commercial butterfly breeders, who supply the exhibition, natural history, education, and special event businesses with butterfly stock, strongly objected to the petition, suggesting it could jeopardize their businesses.  At its core, the petition does strike at the heart of what has made the Monarch butterfly so iconic, widely embraced, and understood–the crowdsourcing utilized to unravel its mysterious migration and the resulting groundswell of interest in conserving it.

Reactions to the move toward threatened status were mixed.

“Could have gone either way,” said Dr. Chip Taylor, founder of Monarch Watch, the citizen scientist program that tags thousands of Monarch butterflies each year. “This finding just means it advances to the review stage and these reviews can be repeated year after year after year for decades. If the current population is as large as I think it is and there is no catastrophic mortality in Mexico this winter, support for the petition could fade. Successful large scale restoration efforts with lots of attendant publicity could also weaken the case for threatened status.” he added.  Taylor has stated his opposition to the petition, calling for an apolitical approach and expressing concerns about landowner backlash if milkweed–the Monarch butterfly’s host plant–is declared critical habitat.

xerceslogo“We are extremely pleased that the federal agency in charge of protecting our nation’s wildlife has recognized the dire situation of the Monarch,” said Sarina Jepsen, endangered species director of the Xerces Society, one of the organizations that submitted the petition. “Protection as a threatened species will enable extensive Monarch habitat recovery on both public and private land,” she added.

Tierra Curry, a senior  scientist at the Center for Biological Diversity echoed those sentiments in this statement posted on the organization’s website:  “The Endangered Species Act is the most powerful tool available to save Monarchs so I’m really happy these amazing butterflies are a step closer to the protection they so desperately need.”

Commercial butterfly breeders were not so thrilled.

ibba“The IBBA does not believe that a status of threatened is appropriate or warranted at this time for the Monarch butterfly,” said the International Butterfly Breeder’s Association president Kathy Marshburn in response to the news. She added that habitat conservation is necessary to support and promote the survival of the Monarch and the IBBA will continue to support these efforts.

The Association For Butterflies, a butterfly education and advocacy group for farmers and hobbyists, issued the following statement:   “The Association for Butterflies is saddened to hear that Fish and Wildlife has decided to move ahead with the process of listing the Monarch butterfly as a threatened species. There is clear evidence that the butterfly itself is not threatened, only the migration phenomenon. Monarch Watch and other organizations are on the right track to help increase the migration numbers by encouraging private citizens and others to plant milkweed, which AFB will continue to support as we work towards helping all pollinators.”

Endangered Species Act Process

So what happens next?

The USFWS will continue to review information, including public comments submitted in the next 60 days. Stakeholders and organizations have two months to express concerns and get them on the public record.

After two-months of public comment, the petition will be considered and evaluated until August 26, 2015 (12 months from the initial filing of the petition) then result in one of the following:

1) USFWS proposes the Monarch for listing
2) USFWS declines to list the Monarch
3) USFWS decides that listing is warranted but precluded by higher priorities, and the Monarch then would be added to a waitlist of candidate species.

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).

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.

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.

Monarch cateripllars

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

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.

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.

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.

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.
