"This book adds to our understanding of caterpillars by providing a means to identify common caterpillars via excellent photos of early stages that are associated with photos of adults, and through snippets of natural history text for each species. This alone will generate enthusiasm for caterpillars among professional biologists and general readers interested in lepidoptera."--Philip J. DeVries, Department of Biological Sciences, University of New Orleans, author of The Butterflies of Costa Rica and Their Natural History, Volumes I and II"This book is an important contribution to the existing knowledge on the lepidoptera of North America, one that should spawn the gathering of new information. It fills a glaring gap in the popular literature on the continent's fauna."--Steven M. Roble, Staff Zoologist, Virginia Department of Conservation and Recreation, Division of Natural Heritage
