This field guide sets a new standard for insect identification, making it an indispensable resource to naturalists, educators, gardeners, and others. Engaging and accessible, Pacific Northwest Insects features detailed species accounts, each with a vivid photograph of a living adult, along with information for distinguishing similar species, allowing the reader to identify more than 3,000 species found from southern British Columbia to northern California and as far east as Montana. The book features most of the commonly encountered insects, spiders, scorpions, millipedes, centipedes, and kin in the Pacific Northwest, as well as representatives of an amazing variety of unusual and interesting insects living in the area. After more than a decade of research, reviewing hundreds of thousands of museum specimens and scouring the technical entomological literature, Merrill Peterson has brought together for the first time in a single volume a wealth of information on the region's insect life. Detailed identifying information on over 3,000 species Complete description of 1,200 species Organized by insect group for easy identification Up-to-date taxonomy 1,725 color photos, 50 line drawings, and 2 maps

FULL COLOR and Enlarged Edition - California has more than twenty-five native species, natural hybrids, and varieties of oaks (Quercus species). The form of these oaks ranges from large trees, up to about 25 m tall, to shrubs no taller than about 1.5 m. California's native oaks include representatives of three oak subgroups or subgenera (Table 1). Hybridization only occurs between oaks in the same subgroup. In addition, some insects, pathogens, and other agents may selectively colonize or damage oaks in certain subgroups.

True ladybirds, classified in the tribe Coccinellini, are easily recognisable by their relatively large and shiny bodies and contrasting colour patterns. They are one of the most widely studied groups of beetles, being of economic importance and used as model organisms in biological and ecological research. Ladybird Beetles of the Australo-Pacific Region covers 22 genera and 95 valid species, including 12 new species, of ladybird beetles from Australia, New Guinea and the Pacific area. For each species, descriptions, illustrations and keys will assist with the correct identification of ladybirds from this large but practically unknown fauna. This book is a valuable contribution to the taxonomy of the ladybirds and to the knowledge of the biodiversity of this unique biogeographic region. It will be of use to entomologists, biologists, ecologists, quarantine officers, natural history museum curators, and students.
