National Audubon Society Field Guide to North American Insects and Spiders - Comprehensive Identification Book for Entomology & Arachnology - Perfect for Nature Lovers, Hikers, and Outdoor Explorers

You cannot go wrong with a book from the Audubon society when it comes to the quality and coverage of cover topic. Furthermore, the physical size of the book is meant to be brought along in the field. I think every family with kids interested in nature should have a series of Audubon books. The same applies to adults spending time in the field wanting to learn. This book very nicely illustrates the different species of insects and spiders in the North America.
