Now there is a guidebook to trees--one of the most popular subjects in the Peterson Field Guide series--for the beginning naturalist. The 243 trees are grouped into six categories by leaf type and arrangement, making it easier for the beginner to identify unknown species. 200 color illustrations.

Here is the first and only guide to a subject of great interest to gardeners, small children, and lepidopterists: caterpillars, the immature form of butterflies and moths. This guide describes 120 common species of these fuzzy creatures. All the caterpillars, their adult forms and many of their host plants are illustrated.
