A Princeton field guide to identification and natural history. At almost 500 pages, it includes 700 species of caterpillars with over 1200 color photos.
Another not yet available guide to caterpillars. I'm slightly bummed because I had visions of creating my own field guide to caterpillars. Given the use my copy of a USDA guide coauthored by Wagner gets, I bet this one will be hard to beat.
Looks like it'll be available in August. Until then I'll just keep it on my Amazon wish list to remind me when the time comes.
