There are about 100,000 kinds of insects in North America, so obviously they can't have a field guide in the same way the 650 species of birds do: something both portable and complete. The National Audubon Society has produced a remarkably useful compromise. This guide has photographs and descriptions of 550 insect species and 60 kinds of spiders. Most of the families of arthropods on the continent are covered, as are all of the most common species. It's a very useful resource for any North American naturalist, and the best choice for an adult who is not an expert entomologist. --Mary Ellen Curtin
From the Inside Flap
Spiders, bugs, moths, butterflies, beetles, bees, flies, dragonflies, grasshoppers, and many other insects are detailed in more than 700 full-color photographs visually arranged by shape and color. Descriptive text includes measurements, diagnostic details, and information on habitat, range, feeding habits, sounds or songs, flight period, web construction, life cycle, behaviors, folklore, and environmental impact. An illustrated key to the insect orders and detailed drawings of the parts of insects, spiders, and butterflies supplement this extensive coverage.
