About Robert Michael Pyle
Born 1947. Robert Michael Pyle is an American lepidopterist.
Robert Michael Pyle (born 19 July 1947) is an American lepidopterist, writer, teacher, and founder of the Xerces Society for Invertebrate Conservation. Much of his life story is told in the 2020 feature film The Dark Divide, where Pyle is played by David Cross.
Early life and education
Pyle grew up in Denver and Aurora, Colorado,
Career Conservation biology and research Pyle worked as ranger-naturalist in Sequoia National Park, butterfly conservation consultant for the Wildlife Division of Papua New Guinea, Northwest Land Steward for The Nature Conservancy, and co-manager of the Species Conservation Monitoring Center in Cambridge, UK, where he co-compiled the IUCN Invertebrate Red Data Book. He has been deeply involved in Monarch butterfly conservation since 1975, convening the First Conference on Monarch Conservation and biology in Morelos, Mexico, and chairing The Monarch Project of the Xerces Society with Lincoln Brower and Melody Mackey Allen. He has also been active in old-growth forest conservation in the Pacific Northwest. These involvements continue. Pyle has published many papers on butterfly conservation ecology and biogeography, and he continues field work as Co-coordinator of the Washington Butterfly Survey. He co-authored (with Paul Hammond) a major paper reviewing the Mariposa Copper butterfly (Lycaena mariposa) and describing nine new subspecies. His most recent paper reports on the behavior of the Woodland Skipper (Ochlodes sylvanoides) during a total eclipse of the sun. Ongoing studies concern forty years of monitoring butterfly phenology at one study site and the biology of a northerly migrant species, both pertaining to climate change.
Teaching and speaking Pyle has taught writing, conservation biology, and natural history seminars for many colleges and institutes around the world, and presented hundreds of invited lectures and keynote addresses. He has served as Visiting Professor of Environmental Writing at Utah State University; as Kittredge Distinguished Visiting Writer at the University of Montana; and as place-based writing instructor for the Aga Khan Humanities Project in Tajikistan and the Writers' Centre of Tasmania.
On twenty-five occasions from 1976 to 2013, he was a presenter and field trip leader at the annual week-long National Wildlife Federation Conservation Summits and their successors, Family Nature Summits. He has also led natural history seminars for Cloud Ridge Naturalists, the North Cascades, Olympic Park, and Glacier Park Institutes, and in numerous other settings.
He has served on the faculty of the Sitka Institute, Fishtrap, Haystack, Art of the Wild, Breadloaf, and many other writers' conferences and events and has led natural history tours for the National Audubon Society, the Smithsonian Institution, the Wilderness Society, the Arizona Sonora Desert Museum, and The Nature Conservancy, and Green & Pleasant Tours ("Birds and Beers of Britain") among others.
Writing Since 1982, Pyle has been an independent scholar, writer, and biologist, concentrating on writing as his primary professional activity. He writes essay, poetry, and fiction from his home along a tributary of the Lower Columbia River in Southwest Washington, where he has lived since 1978. He has published 24 books and hundreds of essays, papers, poems, stories, and anthology chapters.
Pyle's seminal work, Wintergreen: Rambles in a Ravaged Land, describes the devastation caused by unrestrained logging as well as the remaining beauties of his adopted home in the Willapa Hills. His book Where Bigfoot Walks: Crossing the Dark Divide grew out of a Guggenheim Fellowship, and was a major component (along with Pyle's other books) for the 2020 feature film The Dark Divide starring David Cross as Pyle and Debra Messing as his wife Thea Linnaea Pyle. The Thunder Tree: Lessons from An Urban Wildland chronicles the intersection of his Aurora, Colorado, boyhood nature explorations and Colorado's long tradition of water rights battles with the importance of everyone's special places, especially children's. Both Wintergreen and The Thunder Tree exemplify Pyle's love of damaged lands.
His travel narrative Chasing Monarchs: Migrating with the Butterflies of Passage traces his discovery of previously unsuspected monarch butterfly migration patterns. Mariposa Road: The First Butterfly Big Year follows up as another far-ranging butterfly road trip narrative, as it chronicles Pyle's coast-to-coast adventures and misadventures while documenting as many butterflies as possible in one year (similar to a birder's big year). Pyle co-edited and annotated Nabokov’s Butterflies, which collects the novelist's butterfly writings from throughout his literary and scientific opus.
Walking the High Ridge: Life as Field Trip reflects on Pyle's development as a writer and on his sources, influences, and beliefs. Sky Time in Gray's River: Living for Keeps in a Forgotten Place follows the lives of the creatures populating his adopted village month by month through the seasons.
A chapbook of poems and stories, Letting the Flies Out, preceded Pyle's first full-length book of poems, Evolution of the Genus Iris. His second book of poems, Chinook and Chanterelle, features cover art by his wife, the late artist and naturalist Thea Linnaea Pyle. Pyle's third longer collection, The Tidewater Reach: Field Guide to the Lower Columbia River in Poems and Pictures, is a collaboration with photographer Judy VanderMaten.
Other books include The Audubon Society Field Guide to North American Butterflies, The Butterfly Watcher's Handbook, The Butterflies of Cascadia, and The Butterflies of the Pacific Northwest
Magdalena Mountain: A Novel, Pyle's first published book of fiction, weaves a converging tale of disparate personalities brought into the high country of Colorado mountain wilderness by their various quests for the all-black Magdalena alpine butterfly. The book seeks to blend methods of narrative natural history writing with pure fiction by alternating chapters on Magdalena's life in the high rocks with those of the human characters.
Pyle's essays have been collected in three books: The Tangled Bank, his columns from fifty-two consecutive issues of Orion and Orion Afield magazines; Through a Green Lens: Fifty Years of Writing for Nature; and Nature Matrix: New and Selected Essays (September 2020).
Butterfly Launches from Spar Pole, a collaboration of Pyle with Nirvana bassist Krist Novoselic and Ray Prestegard, is an eleven-track audio album of acoustic song-poems inspired by the natural world.
