The West

Jeffrey Glassberg's acclaimed Butterflies Through Binoculars series has essentially revolutionized the way we view butterflies. This new volume, the latest addition to the series, offers expert guidance in locating, identifying, and enjoying all the butterflies of the West. In fact, together with its companion volume Butterflies Through Binoculars: The East, every type of butterfly from the continental United States is described and, in most cases, photographed. As a complement to its outstanding instruction in spotting both rare and common butterfly species, the volume also includes range maps, advice on food plants, wing areas, flight times, and a host of other butterfly facts. Moreover, each stunning photograph contains identification marks, shown clearly for ease in positive identification. From butterfly biology to butterfly conservation, this useful and practical field guide provides all the necessary information to make your butterfly experience a success. Whether you are a butterfly enthusiast, a birder, a conservationist, or a nature lover in general, this volume is the most indispensable item to have on your search for western butterflies.
