Come learn about the fascinating biology of butterflies and caterpillars on Wednesday, April 20, at 7 p.m. at the CU Museum of Natural History. They are much more than airy fragile creatures. Find out what they eat and why, how they taste and smell, how they are different from moths and learn about their arsenal of defenses. This lecture will be presented by Deane Bowers, curator of entomology and professor and chair of the Department of Ecology and Evolutionary Biology at the University of Colorado Boulder.
