Spiders play an essential part of a healthy ecosystem. They are key predators of insect pests—like fleas and mosquitoes—and they serve as prey for other animals, such as birds. If you see spiders in your area, keep this convenient guide close at hand. Designed for ease of use, the spiral-bound booklet is organized by type of spider web for quick identification. Narrow your choices by the web you see, and view just a few spiders at a time. Plus, you’ll also find sections for spiders that don’t utilize webs. The professional photographs showcase 158 species.

Book Features: * Pocket-size format—easier than laminated foldouts * Professional photos showing key markings * Easy-to-use information for even casual observers * The author’s three steps to identifying spiders
