For years this was the best book available for caterpillar identification. It remains a valuable, easy to use identification guide, organized by body type (smooth to hairy and all points in between!).
From the publisher: "This accessible and portable guide contains detailed information on 120 of the most common North American caterpillars, plus illustrations of the adult butterflies and moths they will become. Also included is information on how to raise caterpillars, where to look for them, and what to feed them."
