This engaging and easy-to-use natural history guidebook provides a thorough overview of native and honey bee biology and offers tools for identifying the most common bees of California and the Western United States. Full-color illustrations introduce readers to more than 30 genera of native bees, noting each one's needs and habits and placing them in their wider context. The author highlights beesÕ ties to our own lives, the food we eat, and the habitat we provide, and suggests ways to support bees in our own backyards. In addition to helping readers understand and distinguish among major groups of bees, this guide reveals how bees are an essential part of healthy ecosystem and how many plants, including important crop plants, depend on the pollination they provide. As growing evidence points to declining bee populations, this book offers critical information about the bond between plants and pollinators, and between humans and nature. Thoroughly researched and full of new insights into the ancient process of pollination, Field Guide to the Common Bees of California; Including Bees of the Western United States is invaluable for the window it opens onto the biodiversity, adaptive range, and complexity of invertebrate communities.

With over 40,000 described species, spiders have adapted to nearly every terrestrial environment across the globe. Over half of the world’s spider families live within the three contiguous Pacific Coast states—not surprising considering the wide variety of habitats, from mountain meadows and desert dunes to redwood forests and massive urban centers. This beautifully illustrated, accessible guide covers all of the families and many of the genera found along the Pacific Coast, including introduced species and common garden spiders. The author provides readers with tools for identifying many of the region’s spiders to family, and when possible, genus and species. He discusses taxonomy, distribution, and natural history as well as what is known of the habits of the spiders, the characters of families, and references to taxonomic revisions of the pertinent genera. Full-color plates for each family bring to life the incredible diversity of this ancient arachnid order.

"Two of North America's most prolific and respected specialists on moths--particularly those of the West--have combined over a century of experience and scholarship to introduce western moths of all families authoritatively to both the amateur and the experienced professional entomologist. This biologically oriented and beautifully illustrated treatment of a quarter of all known western moth species fills a long-needed void, and does it superbly."--Charles V. Covell Jr., author of A Field Guide to Moths of Eastern North America "This work sets a new high water mark for North American lepidopterology. Considering the authors' century of combined studies of western Lepidoptera, it is clear from the outset that no other team could have delivered a work so rich in taxonomic and life history information, much of it being original and appearing in the literature for the first time. I will read my copy more like a novel than a reference work, casting about the accounts and repeatedly flipping through the 2300 color images to better familiarize myself with our continent's rich and handsome diversity of moths. Moths of Western North America will serve as both gateway and catalyst for the study of moths for decades, and especially for microlepidopterans--for whom no like work exists in the New World."--David L. Wagner, author of Caterpillars of Eastern North America "Recent years have seen a surge of interest in moths, with growing appreciation of their amazing diversity and their great ecological importance. Information on western moths has been scattered and scarce, however, so this new volume is a tremendous step forward. Jerry Powell and Paul Opler bring a vast amount of knowledge and experience to the subject, and their Moths of Western North America is a landmark publication, instantly indispensable to anyone with a serious interest in Lepidoptera."--Kenn Kaufman, coauthor of Kaufman Field Guide to Butterflies of North America

"Covers all 416 species of flower flies that occur north of Tennessee and east of the Dakotas, including the high Arctic and Greenland"--Page [4] of cover.
