Monarchs are the best-known butterflies, recognized across the country by their conspicuous orange and black pattern, and many people saw them this summer. Come hear Dr. Ernest Williams speak about their remarkable migration, habitat needs, trends and controversies about their abundance, and conservation initiatives underway to counter their long-term decline.
A biologist at Hamilton College for the past 35 years, Ernest Williams studies the population biology and conservation of butterflies. His fieldwork has focused on monarch butterflies at their Mexican overwintering sites, frosted elfin butterflies in central New York sand plains, and checkerspot butterflies in Rocky Mountain meadows. His books include The Nature Handbook: A Guide to Observing the Great Outdoors (2005, Oxford University Press), and he is also co-author of The Stokes Butterfly Book (1991) and editor of Pathways to Excellence in Teaching (2012).
