Postscript to the Butterfly Big Year Blogs: Not Far Tortuga, But Close

Dear Folks,

The trip is finished, and so are the blogs, but I wanted to provide a brief coda to bring it all back home. As you know, the Orion and Xerces blogs have carried different, complementary content all along, But for this little epilog, I’ve decided to send a single note to both sources, and to do it with electrons via Thea’s computer. Forgive me for not mailing any doodads or tree trunks or trash bits from the road this time. I came home to our biggest snow in thirty years, which melted and rained and blew into one of our biggest floods within just 48 hours, and the road to the post office has been blocked by deep, rushing water. So here, in conventional fashion, is a wrap-up to the whole deal:

The Christmas blizzard in Portland barely let me out of town, and Chicago was worse, with hundreds of stranded holiday evacuees still stashed and crashed around O’Hare wherever they could find prone space. Yet I made it to Fort Lauderdale only a day late, where the incomparable Alana Edwards picked me up. Alana and her mother Lana, bright lights in the Atala Chapter of NABA, made my valedictory trip to Florida possible. Alana had arranged permits and transportation, including the rangers’ boat to stilll-wild Lignum Vitae Key. For the next few days, we prowled hammocks and mangroves in the Glades and the Keys in search of butterflies I’d not yet encountered.

I had hoped to venture out to Dry Tortuga National Park, to see out the year in the most distal point of the U.S. However, time, expense, and the paucity of butterflies there all militated against a Tortugan finish. The next farthest place I could go, where I’d never been before and where exotic (=outlandish) species of butterflies drifted or blown in from Cuba or elsewhere in the Antilles are always possible, was Key West. Alana kindly and heroically fought the holiday traffic (early mornings helped) to get me there, with interim outings on several of the Keys. Well acquainted with the butterflies, the plants, and the places, and extraordinarily observant, Alana was the best of guides. Among other naturalists we met, resident butterflier, gardener, artist, and devoted conservationist Paula Cannon joined us, and led us to remnant habitats she’s worked hard to save. At her tranquil home on a quay in the Keys, Paula prepared and served us elegant, slender silver fish that she and her husband Gary had caught in local waters, with the wonderful name of look-down fish.

While only a few of the possible new species deigned to show up, they were very special ones: the brilliant Florida purplewing shining in dappled sunlight on Lignum Vitae; the endangered Miami blue, just one among hundreds of Cassius blues, on little Bahia Honda; and the bright, long-tailed Bartram’s hairstreak, which I’d been seeking off and on since early spring, right where we hoped it would be on Big Pine Key. We toasted them all with Florida ale (some the year’s last) at the notorious No Name Pub on tiny No Name Key. These rare butterflies have survived, maybe just, in spite of the over-zealous burning of pine rockland, mosquito spraying, and overall development of these overloved and undervalued islets. Horny hordes of Jurassic-looking iguanas throng the Keys, released and escaped and now all but in charge, skinning nickerbean and other butterfly host-plants from the thin coral soil. Hurricanes, too, have wiped habitats free of structure and diversity. But perversely, sea heliotrope has proliferated along the beach of Big Pine since Hurricane Wilma, attracting a spectacular showing of big, bright hammock and mangrove skippers, tropic queens, and Martial’s hairstreaks. We reveled in the waning year’s last butterfly throes. For me, anyway. Down here, they never stop.

Of course, I could have seen more novel species had I just remained in Texas: my friends in the Lower Rio Grande Valley spotted more than a dozen that would have been new for me within days of my departure. But then I would have missed Hawaii with Thea, Arctic Portland with our family, and this splendid immersion among these shimmering denizens of Old Florida, and those who love, study, and care for them and their besieged habitats. And has anyone else ever had the astonishing good fortune to seek butterflies on both Kaua’i and the Keys in the same week?

Masses of butterflies accompanied me down to Key West and all around it, and I enjoyed them fully, knowing they’d be the last, and have to last me, for a long time. Even greater masses of human beings filled the final Key for its noted New Year’s blast. I mostly managed to escape them, finding tucked-away habitats among the city’s nature reserves, ancient salt flats and the remoter fringes of Civil War-era Fort Zachary Taylor, where mangrove buckeyes flickered and hundreds of various yellows mocked the winter. But the most exciting butterfly–what a finish if it had lingered, instead of sailing away far over a condo!–appeared at a patch of Spanish needles in a vacant lot by a busy intersection: a mystery beauty that to my eyes most resembled a Hypanartia, or mapwing: a tropical genus recorded no nearer than Cuba or Veracruz.

Just east of the spot billed “as the southernmost point in the U.S.” lies South Beach–some ways southward of the one where diet came from. There, my feet in the sea, my butt on an algal-green coral slab, I watched the sun set on the year and the venture. When the last gulf fritillary, cloudless sulphur, and fiery skipper went to roost, I’d tallied 488 species, unofficially–489, if you count the mystery nymphalid that came and went over the Caribbean. The last sun of 2008 disappeared into a diffuse pink contrail from Havana, and that was that.

Of course I couldn’t quite escape the New Year’s craziness of Key West, from the drag diva named Sushi (another species of tropic queen) who descends in a big red high-heeled shoe at midnight, to the lightly clad legions promenading Duval Street in a viscous flow of sweat, skin, drink, and cigar smoke, all but impenetrable for an outlander with backpack and a butterfly net, complete with aluminum extendable handle. Pity I’d shed the tiki torch in Portland: it would have fit right in. I took refuge on the sofa of an Irish pub called Bogart’s until four A.M., when the bars closed, the human cacophony subsided, and the many feral roosters (just as in Hawai’i: here was the real link between Kaua’i and the Keys) began to crow. I recall a moment in there when an inebriated and pretty young blonde launched herself onto my lap with vigor, and another when a fellow leaned in from the street to insist that I was Ernest Hemingway resurrected. Those were the high points of an evening that suffered, on the whole, in contrast with that charmed week’s final field trips.

I found a tree in a secluded part of the fort with spreading roots that welcomed me for a couple of hours of sleep. And in the morning, after I’d mollified both the Navy folks and the State Park ranger who challenged my presence there, I discovered an isolated cove where I bathed, swam, and watched a great southern white fly off across the Straits of Florida. Then I greeted the New Year among a school of beautiful pipefish, their long, thin bills and tails the same color as the sea that stretched away toward far Tortuga.

***

I want to thank Hal Clifford and Scott Walker at Orion Magazine, and Sean Tenney and Sarina Jepsen at the Xerces Society, for their heroic stewardship of my motley materials to produce these weblogs of the first Butterfly Big Year; and for their generosity in sharing interlinks and this final entry between them. Especially, I am thankful to those of you who have read and followed along with me on this long strange trip in the charmed company of butterflies, or not. I hope what has come through more than anything is the sense of extreme privilege I have felt in spending a year of my life this way. I am deeply grateful to Orion and Xerces for allowing me to share it with you in this medium. There is much, much more to tell–but for that, you’ll just have to read the book. Happy New Year, and keep an eye out for butterflies in aught-nine,

Bob

The Xerces Society Postscript to the Butterfly Big Year Blogs: Not Far Tortuga, But Close - The Xerces Society

Announcing the 2019 DeWind Awardees

The Xerces Society has always been a champion for butterflies; not only are we named after a butterfly, but also butterfly conservation formed our very foundation. As a recipient of a Fulbright-Hays scholarship to Britain in the 1970s, a young Robert Michael Pyle was inspired by a talk he heard about the endangered large blue (Maculinea arion) in England. The US had lost its own blue butterfly, the Xerces blue (Glaucopsyche xerces), and Bob was determined to take action to ensure other butterflies did not follow the same fate. Ideas took root on a train ride following the talk, and over the next few weeks and months connections were made, plans developed, and the Xerces Society blossomed. Over the years, the organization’s work expanded to include other terrestrial insects like moths and bees, and we now work on behalf of all invertebrates, including everything from bumble bees and other pollinators to stoneflies, fireflies, and freshwater mussels.

Joan Mosenthal Dewind

However, back in the 1970s, our focus was butterflies. The Xerces Society was powered in those fledgling years by an eclectic group of passionate conservationists. One of our pioneering members, Joan Mosenthal DeWind, was an avid butterfly gardener and accomplished amateur lepidopterist. A psychiatric social worker by day, in her spare time Joan championed butterfly conservation and strove to engage the next generation of butterfly enthusiasts. Joan and her husband Bill DeWind—a New York activist attorney—played an integral role in Xerces’ early years as a developing organization, with Joan serving as secretary, Bill providing legal advice, and both of them joining fundraising fieldtrips. Joan was also a talented artist and writer, and she and Jo Brewer, one of Xerces’ cofounders, often conspired together on early publications.

Throughout her life, Joan was known for her generosity. After she passed away in 1997, Bill established a research endowment fund in her name and asked Xerces to manage a grant program that would support student research to advance the conservation of butterflies and moths around the world. This grant—the Joan Mosenthal DeWind Award—has been given to at least two students every year since the program launched in 1999. In total, 44 students have been recipients of Bill and Joan’s generosity.

The requirements for the DeWind award are broad: applicants must be engaged in research leading to a university degree related to Lepidoptera conservation, with the intention to continue in this path after graduation. The proposal period opens around the beginning of November each year and closes two months later. During this time, applications come in from all over the world for a wide variety of projects. Our DeWind committee, made up of university professors and researchers who work closely in the Lepidoptera conservation world, reviews each of the proposals and ranks them based on quality of science and impact on Lepidoptera conservation. Award winners are selected and notified in the spring.

Previous DeWind awardees have studied everything from climate change effects on geometrid moths to mutualistic relationships between ants and blue butterflies. Research projects may take place in the field, the lab, or a combination of the two. Funded work has taken place across a broad geographic and ecological scope, as awardees have hailed not only from the US and Canada but from Brazil, Singapore, and the Czech Republic. It is exciting to review the breadth of proposed projects each year, to see trends in research topics and integration of new techniques and information. Our hope has always been that the work supported by the DeWind award will have broad implications for Lepidoptera conservation—students tackling big questions with real-world solutions.

The DeWind committee has wrapped up their reviews of this year’s proposals, and the Xerces Society is happy to announce the two recipients of our 2019 awards.

Niranjana Krishnan, a PhD candidate at Iowa State University, will receive an award for her project “Assessing the risk of insecticides to monarch butterflies.” Monarch butterfly populations have declined precipitously in the last few decades, resulting in a nationwide call to action to protect monarch resources and plant additional milkweed (the monarch’s host plant) in important breeding areas. Agricultural regions of the Midwest have been identified as particularly important breeding grounds for the monarch’s eastern population, yet relatively little is known about how agricultural pesticides affect monarchs. Knowing where and how to incorporate milkweed in this landscape will be a critical component of this species’ recovery plan. Krishnan will use funds from the DeWind award to evaluate the toxicity and exposure of agricultural insecticides to various life stages of monarch butterflies, using the information gleaned to help identify ideal locations for plantings.

Our second awardee, Molly Wiebush, is a master’s student at Florida State University. Wiebush’s project, “The importance of small-scale fire refugia for butterfly communities in an old-growth longleaf pine savanna,” examines how these butterfly communities respond to unburned patches within prescribed burns. Do unburned patches (i.e., fire refugia) contribute to the persistence of butterflies in fire-adapted landscapes? How important is small-scale heterogeneity for butterfly survival under different fire scenarios? This project also has broad conservation implications, since it can inform best management practices for using prescribed fire as a conservation tool for Lepidoptera.

The Xerces Society is proud to support young and early career researchers through Joan’s legacy. As a science-driven conservation organization, we take pride in engaging students in the scientific process while advancing our collective knowledge in support of Lepidoptera conservation efforts. It is our hope that the data collected for these projects do not end with the student’s thesis or dissertation; but rather that awardees will go on to publish their research in peer-reviewed journals, share and apply this knowledge where applicable, and pursue a career that continues to support conservation of this incredible group of animals.

If you are a student, or know a student who might be interested in this award, we encourage you to look out for our annual announcement, which goes out in late October or early November every year. This is posted on both the Xerces website and social media outlets, as well as on listservs such as Ecolog-L. To date, all but one recipient have been graduate students, but we encourage motivated undergrads whose studies could have broad impacts on Lepidoptera conservation to apply.

Dewind awardees often go on to publish their research in peer-reviewed journals including Conservation Biology, Ecology, Evolution, and the Journal of Insect Conservation. A growing list of publications by DeWind recipients is also available on our website.

National Butterfly Center Gets Reprieve—But Border Wall Will Impact Much More

The building of a wall along the United States–Mexico border has become a topic of debate, in both private and public spheres. The majority of Americans (58%) oppose the border wall for a variety of social, economic, and environmental reasons. Political disputes over border wall funding also led to the record-breaking 35-day government shutdown from December 22, 2018 to January 25, 2019—which negatively affected hundreds of thousands of people and the services of several federal agencies—and still rumble on within Washington, D.C., as this blog is published. All of these are significant concerns, but as a conservation organization, the Xerces Society’s focus is on the border wall’s environmental implications.

Recently, debate about the potential environmental impacts of the border wall has been in the spotlight because construction would impact the National Butterfly Center, near Mission, Texas. The Xerces Society opposed putting the wall across the Center, and joined in calling for the federal government to reconsider moving forward with construction. The good news is that the Center appears to have a reprieve: The government funding bill approved by congress includes a ban on building the wall through several sites in the Lower Rio Grande Valley, including the National Butterfly Center.

The National Butterfly Center has been at the center of debate over the border wall. The threat of construction has apparently been lifted thanks to a clause in the government funding bill passed by Congress. (Photos: Xerces Society / Ray Moranz)

However, the National Butterfly Center is a microcosm of what will happen on a larger environmental scale as a result of the border wall—even if only parts of the wall are built. And with news reports that President Trump will sign the funding bill today and declare a national emergency, this debate becomes more timely and urgent.

Over the past few decades, the Department of Homeland Security has already constructed 605 miles (974 kilometers) of border barriers. Because the total length of the continental border is 1,954 miles (3,145 km), more than 1,300 miles (2,090 kilometers) of barrier could still be built if the current administration has their way. In preparation, the DHS has been waiving all regulations that could hinder wall construction due to environmental, archeological, or cultural reasons—a list of some 27 acts including the Endangered Species Act, Clean Water Act, National Historic Preservation Act, and Native American Graves Protection and Repatriation Act—setting a dangerous precedent of eroding key protections.

In addition to the policy implications of the border wall, there are other serious potential impacts for wildlife—especially species that need to move across the region to access habitat or to find mates. For them, the political construct of an international border has no meaning, but nevertheless the construction of a wall could be catastrophic. For instance, the jaguar (Panthera onca) and ocelot (Leopardus pardalis) are already threatened with extinction, and the border wall would add an additional stressor.

Similarly, some people have expressed concern about monarchs and other butterflies being unable to migrate or move over the wall. Although that is not a concern for most bee or butterfly species (including monarchs), there are some species that are low-flying, and whose movements could be hindered by a border barrier. The endangered Quino checkerspot butterfly (Euphydryas editha quino) is one example. The Quino checkerspot’s known populations straddle the border between California and Mexico and would be divided by the wall.

The real issue, however, is the loss of local habitat due to construction of the wall. New barriers and associated infrastructure will directly destroy tens of thousands of acres in some of the most diverse habitats in North America—undoubtedly negatively affecting local species. Although many media images have shown tall, narrow concrete and steel barriers, the border wall will impact a much wider swath of land—including the construction of service roads and associated buildings, and clearing vegetation on both sides of the barrier for visibility and ease of access. This is based partly on what has already occurred: the 605 miles of already-existing border barriers are serviced by 4,970 miles (8,000 kilometers) of roads, as well as thousands of miles of undesignated routes created by off-road patrol vehicles. Indeed, a recently published paper in Bioscience details the potential impacts of construction of the wall and associated infrastructure, including: the elimination or degradation of natural vegetation, killing animals both directly and through habitat loss, fragmenting habitats (thereby subdividing populations into smaller, more vulnerable units), and reducing habitat connectivity. According to the Bioscience paper, the wall could also change wildfire patterns.

The wall and associated infrastructure will also include nighttime lighting, which can disorient moths and other night flying insects that are vital food sources for species from birds to bats. Meanwhile, already-existing spans of border fence have “acted as dams in rainy season flash floods,” as detailed in this piece by National Geographic—notably causing damage to Organ Pipe Cactus National Monument in Arizona in 2008. The Bioscience paper also discusses this topic, raising concerns of soil erosion and the alteration of hydrological processes (e.g., floods) if the border barrier is expanded.

The U.S.-Mexico border wall will cut across the landscape, bisecting landforms and habitats. This section is in Arizona; Mexico is to the left of the fence and access road. (Photo: Miguel Angel de la Cueva, Wikimedia.)

It is not just any land that will be impacted. In addition to family farms and other private property, the wall will negatively affect many areas that are species-rich and ecologically sensitive. Indeed, many animals and plant populations will be threatened if the wall is built. The Bioscience paper estimates that, if completed, the administration’s plan will bisect the geographic ranges of 1,506 native terrestrial and freshwater animal and plant species, including 62 species listed as Critically Endangered, Endangered, or Vulnerable by the International Union for Conservation of Nature (IUCN) Red List.

The 1,500+ species listed in the paper include 199 invertebrates (178 insects, 11 snails and slugs, 9 aquatic mollusks, and 1 spider). Unfortunately, the paper likely underestimates the number of insects and other invertebrates that will be impacted, as the data is simply not available to assess most invertebrate species. Insects and other invertebrates are the least well-studied animals, and their ranges are not well-documented. We do know, however, that on a global level insects outnumber mammals 150:1—there are approximately 6,500 documented mammal species and almost 1 million documented insects. Considering that 163 mammal species are documented within the footprint of the border barrier area, there could potentially be over 24,000 insect species within the same area. (This estimate does not include invertebrates like mollusks and crustaceans.) Especially when you consider that the lands along the border also have relatively high butterfly and bee diversity, it is clear that the border wall’s impact on insects could be substantial.

"There are many reasons to oppose the wall along the southern border—including the loss of habitat for some of our smallest and most important animals." - Scott Hoffman Black, Xerces Society Executive Director

In short, there are many reasons to oppose the wall along the southern border—including the loss of habitat for some of our smallest and most important animals. Accordingly, scientists and conservationists are adding their voices in opposition to the proposed border wall. Defenders of Wildlife organized an effort to encourage scientists to speak up on this issue. As part of that effort they helped publish the Bioscience article, which states:

“We urge the US government to recognize and give high priority to conserving the ecological, economic, political, and cultural value of the US–Mexico borderlands. National security can and must be pursued with an approach that preserves our natural heritage.”

This paper has been signed by more than 2,900 scientists, including some from the Xerces Society.

In the face of mounting environmental challenges, the Xerces Society will continue to focus our attention on protecting, restoring, and enhancing habitat for invertebrates in all landscapes—urban and rural, farms and cities, roadsides and wildlands—so we can maintain invertebrate biodiversity for generations to come.

Monarch Butterflies in Western North America in Jeopardy

Population of monarchs overwintering in California at lowest level ever recorded


Media Contacts:

Emma Pelton, Endangered Species Conservation Biologist; emma.pelton@xerces.org, (971) 533-7245

Sarina Jepsen, Endangered Species Program Director; sarina.jepsen@xerces.org, (971) 244-3727


PORTLAND, Ore.; Thursday, 1/17/19—The population of monarch butterflies overwintering in California has fallen to the lowest level ever recorded. Surveys done by volunteers with the Western Monarch Thanksgiving Count found only 28,429 butterflies, an 85.2% fall from the previous year—and a 99.4% decline from the number of monarchs in the state in the 1980s. The results of the count were released Thursday by the Xerces Society for Invertebrate Conservation, along with a Western Monarch Call to Action.

“To picture what this means for monarchs, imagine that the population of Los Angeles had shrunk to that of the town of Monterey,” said Emma Pelton, a monarch conservation expert with the Xerces Society.

Faced with these alarming numbers, Pelton has worked with monarch scientists at institutions across the West to develop the Western Monarch Call to Action, a five-point rapid-response action plan to rescue the western population of the monarch butterfly.

The most immediate priority in the coming weeks is to ensure monarchs have nectar to fuel their flight and milkweeds on which they can lay their eggs when they leave the overwintering sites. This is something that everyone in California can help with right now: plant early blooming native flowers and milkweed to restore breeding and migratory habitat. Monarchs will use plants growing in gardens, parks, along railroads, on farms and anywhere else they can find them.

“It’s easy to give up when faced with news like this,” said Pelton. “But doing nothing is not an option.”

Of equal importance to ensuring monarchs have flowers is protecting their overwintering sites. Each year, the groves they shelter in are destroyed or damaged by development or inappropriate tree trimming. This needs to be halted and the groves given adequate protection and management, so that monarchs have a place to return to next fall.

There are important questions that remain unanswered about monarchs, such as a detailed understanding of where they go right after they leave the overwintering sites. People can watch out for monarchs and report what they see to the online Western Monarch Milkweed Mapper project to help inform conservation strategies.

Other important actions include reducing pesticide use, so monarch have clean places to feed and breed, and identifying and enhancing areas across the western states where monarchs fly to during the summer.

Many state and federal agencies, farmers, nonprofits and individuals are increasing their conservation efforts, but more work needs to be done.

“Saving the western monarch migration is not something that the Xerces Society can do alone” said Sarina Jepsen, director of the Xerces Society’s endangered species program. “There are things that can be done by anyone in any place. We urge you to join us and our colleagues in the western monarch science and conservation community in taking meaningful, swift action to help save western monarchs.”

The Xerces Society is taking action to protect the western population of monarchs. Xerces is pushing for protection of overwintering sites and working with partners to restore overwintering habitat near the coast. Also, working with farmers, natural area managers, California cities and others, we are planting and restoring habitat across the Central Valley—a key breeding and migration area for monarchs. In the last 18 months, we have restored 20 miles of hedgerows on farms, and in the coming year, we will be adding another 10 miles to further re-connect habitats. These hedgerows provide essential nectar sources, milkweed for breeding, and unsprayed refuge.

Xerces staff are working with the USDA-Natural Resources Conservation Service Plant Materials Center in California to conduct planting trials of milkweed and monarch nectar plants to develop best practices for establishing these plants in the state.

“Can we promise that monarchs will recover and fill California’s skies again?” said Xerces Society Executive Director Scott Hoffman Black. “Sadly, no. But we are not going to be the generation that witnessed this loss and stood by and did nothing.”

It is urgent that we focus on conservation across California and the west if we hope to have the best chance to save the western monarch migratory phenomenon, the overwintering aggregations and the tourist dollars that benefit California from visitors coming to see clustering monarchs.

The monarch population in eastern United States and which migrates to Mexico has declined by more than 80% in the last 20 years, but has not suffered the same alarming fall in numbers this year.
