Few people appreciate the diversity of insect life, and most naturalists, including professionally trained biologists who work with vertebrates or flowering plants, are surprised, even skeptical, when they hear estimated numbers of insect species. There are believed to be about 1.5 million named and described species of insects worldwide, which is more than five times the number of all other animals combined.
In this text we summarize the diversity, taxonomy, and larval biology of western North American moths. The introductory sections give general features of the morphology of adults and immature stages and summarize adult behavior, larval biology, and life cycles. In this book, inspired by I. F. B. Commonís Moths of Australia, we have taken an innovative approach as compared to previous treatments of Nearctic Lepidoptera. We attempt comparable treatment of all moth families, irrespective of the size of the moths or their traditional popularity with collectors.
