Butterflies are largely admired for their beauty and grace, but are rarely recognized for their variety of physical, chemical, and behavioral adaptations that increase their survival rates. This program is designed to discuss these defense strategies along with photos and anecdotes from the travels of Dr. Glenn Crisler’s travels across the eastern USA.

Dr. Glenn Crisler II is an analytical chemist with a deep passion for lepidoptery. Glenn is an avid naturalist who leads outdoor hikes and delivers lectures for various organizations. He is on a mission to photograph all the butterfly species of the eastern USA. Some of his findings have been featured in News of the Lepidopterist’s Society and the Society of Kentucky Lepidopterists.
