   Our guest speaker will be Herb Wilson, co-author of the new book Butterflies of Maine and the Canadian Maritime Provinces. He is a Professor Emeritus of Biology at Colby College where he taught Ornithology, Evolution and Diversity, Marine Ecology and Invertebrate Zoology for 30 years. His primary ornithological interests are the impacts of global climate change on bird migration and the foraging behavior of winter birds in Maine. He is also keenly interested in the butterflies and odonates of Maine.
   His talk will center around the findings presented in the Butterflies of Maine and the Canadian Maritime Provinces, published this fall by the Cornell University Press. This publication is based on a citizen-science project (the Maine Butterfly Survey) with field work conducted between 2003 and 2019. A number of MBC members contributed to the project.
   We'll begin with a brief history of butterfly study in Maine and review our diversity. Then, we'll explore the changes in distribution of many species, including a new North American record and other state records as well as the extirpation of some species. We'll look at the importance of habitat in determining the presence of different butterfly species and conclude with an exploration of the effects of climate change on butterfly distribution.

Butterflies of Maine Butterflies of Maine and the Canadian Maritime Provinces introduces readers to over one hundred and twenty butterfly species documented in the Acadian region.

MassWildlife staff recently discovered a frosted elfin caterpillar at Montague Plains Wildlife Management Area after 2 decades of habitat restoration at the site. This exciting find is evidence that these efforts are paying off. See this link for more information.
