A Study Of The Leaf Mining Diptera Of North America

The first-ever reference to the sign left by insects and other North American invertebrates includes descriptions and almost 1,000 color photos of tracks, egg cases, nests, feeding signs, galls, webs, burrows, and signs of predation. Identification is made to the family level, sometimes to the genus or species. It's an invaluable guide for wildlife professionals, naturalists, students, and insect specialists.
