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

Declines in Insect Abundance and Diversity: We Know Enough to Act Now—New Paper Details Why We Need to Act to Protect Insects

Declines in Insect Abundance and Diversity: We Know Enough to Act Now

New paper details why we need to act to protect insects.

PORTLAND, Ore.; June 24, 2019—On Saturday, June 22, the journal Conservation Science and Practice published a paper that makes the case for greater action to curb the global decline in insects. Insects are vital to life as we know it on this planet. The vast majority of bats, birds, and freshwater fish depend on insects, and humans depend on insect pollination for nutritious fruits and vegetables. Insects provide services of over $57 billion to the US economy. Although we need more study to understand the overall scope and scale of the declines, the research that has been done provides compelling evidence of declines in insect abundance, diversity, and biomass.

“There is no doubt that a great many insect populations and species are suffering and are in some form of decline,” said Matt Forister, McMinn Professor of Biology, University of Nevada, Reno. “Although there is a need for greater investment in basic science and further analyses of existing data, our belief is that the severity of reported insect declines is sufficient to warrant immediate action.”

In addition to the data supporting the decline of insect populations, patterns are emerging that point to the primary drivers of insect declines. The most influential factors are habitat loss and degradation, pesticides, and climate change, although other factors include disease, invasive species, and light pollution.

“There are many factors leading to the decline in insects,” said Emma Pelton, endangered species conservation biologist and western monarch lead for the Xerces Society for Invertebrate Conservation. “Even though there are still unknowns, taking action to restore, enhance, and protect habitat and curbing pesticides has been shown to help insect populations.”

The paper not only presents the problem, but also provides examples of success stories in insect conservation, from both terrestrial and aquatic environments spanning three continents. The authors also propose actions that can be taken to address insect declines, which can be implemented by various societal sectors including nations, states, provinces and cities, working lands, natural areas, and homes and gardens.

“If we hope to stem the losses of insect diversity and the services they provide, society must take steps at all levels to protect, restore, and enhance habitat for insects across landscapes—from wildlands to farmland to urban cores,” said Scott Hoffman Black, executive director of the Xerces Society. “But there is hope because everyone can make a difference. Farmers can add additional habitat and curb pesticide use, governments can make climate adaptation a goal, and even a backyard or apartment balcony can be an important stopover for the smallest of animals upon which we all depend.”

Emergency Endangered Species Act Protection Sought for Delaware Firefly

For Immediate Release

BETHANY BEACH, Del.; May 15, 2019The Center for Biological Diversity and the Xerces Society for Invertebrate Conservation filed an emergency petition today seeking Endangered Species Act protection for the critically imperiled Bethany Beach firefly.

The rare firefly has been documented at only seven sites along the Delaware coast  virtually all of them smaller than a football field. The wetland area that is home to the firefly’s largest-remaining population is currently being developed.

If the U.S. Fish and Wildlife Service grants the emergency request it would be the first time Endangered Species Act protections have been awarded to one of the nation’s approximately 170 firefly species.

“Without immediate protections, the magical green flashes known to generations of children will be snuffed out forever,” said Dr. Tara Cornelisse, an entomologist who is a senior scientist at the Center. “We can’t stand by and let development, climate change and pesticides wipe out these amazing creatures, along with their wetland homes that many species depend on.”

The Bethany Beach firefly has been pushed to the brink of extinction by urbanization, light pollution, habitat fragmentation, pesticides and climate change-induced sea-level rise and storm surges.

The firefly has nearly disappeared from three of its seven remaining sites. Six of the firefly’s seven remaining populations are in state parks, but only a single firefly was found at two of those sites during the most recent survey.

“We’re on the brink of losing a unique piece of Delaware’s biodiversity, one that symbolizes the very habitats that have drawn so many people to this state in the first place,” said Candace Fallon, petition coauthor and senior conservation biologist at the Xerces Society. “There’s no question that this firefly urgently needs our help to prevent it from going extinct.”

Ongoing construction at the Tower Shores development continues to destroy important habitat for the firefly’s strongest remaining population. Loss of that population would greatly lessen the species’ chances of survival because these fireflies are weak fliers and rarely disperse beyond the habitat in which they were born.

When a population is lost it severely decreases connectivity between habitats, potentially reducing the number of mates available and, in turn, the number of eggs laid by females.

Background

The Bethany Beach firefly is only found within 1,500 feet of the shore, making its habitat extremely vulnerable to rising sea levels and increases in storm surges caused by climate change. The combination of higher water levels near housing developments and popular recreation areas has resulted in frequent spraying of pesticides to control mosquitoes with chemicals toxic to fireflies.

The Bethany Beach firefly flies at full darkness so that females can spot and blink in response to a male’s bright double green flash. After mating the females will continue to flash, but this time mimicking other firefly species to lure in males to eat them and gain their valuable protective toxins. These mating signals can be disrupted by habitat changes, and light pollution can change their courtship behavior and mating success.

Firefly larvae sometimes hunt communally, and feed on slugs, snails, earthworms and other insects by injecting paralyzing fluid before consuming their prey.

Fireflies live on every continent except Antarctica. But just as in Delaware, many of their populations are threatened by habitat destruction, light pollution, climate change and pesticides.

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.
