Lee. A. Dyer is an ecologist who has worked with Lepidoptera—focusing on immature stages—in tropical and temperate ecosystems for the past few decades. He received a BSc in biochemistry and a BA in english from the University of California (UC) Santa Barbara and then spent 6 years traveling, rock climbing, writing poetry, and working on environmental issues before deciding to go to graduate school. His PhD research at the University of Colorado, Boulder, examined chemically mediated interactions between plants, herbivores, and their natural enemies and included work in Costa Rica, Colorado, and California. Lee spends his free time looking for caterpillars, hanging out with his family, rock climbing, listening to music, drinking red wine, writing poetry, and reading books.Matthew L. Forister is an evolutionary ecologist in the Biology Department at the University of Nevada, Reno. He received a BA in Englishwriting from the University of San Francisco, spent 2 years with the Peace Corps in Ukraine, and then earned a PhD in ecology from UC Davis. He studies herbivory, diversity, and hybridization, and has worked with different plants, animals, and fungi across temperate and tropical ecosytems, but particularly loves the blues, coppers, and hairstreaks (family Lycaenidae) and their humble but fascinating caterpillars and the ants that keep them safe. When not chasing butterflies, he favors old novels, the mountains of the Great Basin, and hanging out on the porch with his family, Beth and Catalina.
