The National Audubon Society Field Guide to North American Insects and Spiders is a guide detailing North American Insects and Spiders.
First, the good points. The photographs in this book are superb and the guide is fairly well organized. It's also small enough to fit into a largish pocket.
Now, the not so good points. There weren't nearly enough entries, specifically regarding the spiders. While the organization was good, there were small parts that seemed illogical.
However, the litmus test for a field guide is its usefulness and fortunately, I've taken quite a few photos of insects and spiders. Here come the bug pictures!
