Annual migrations of some kinds of North American butterflies and dragonflies (as well as birds!) are well known and often highly popularized. However, perhaps one of the most interesting migration stories in North America involves the army cutworm with its low elevation/high elevation migration cycle that occurs entirely within the borders of the United States and is most clearly evident in eastern Colorado. The focus of this evening’s discussion will be this rather notorious “miller moth” and explore the life history and habits of this insect and the various impacts it has on ecology and human interests.

Whitney Cranshaw is presently an emeritus professor of entomology at Colorado State University, following retirement in July 2020. During his 37 years at Colorado State he primarily worked on issues related to the better understanding and management of insects that affected horticultural plants in the state.
