A lovely little book, just under 100 pages. Covers all 69 species/forms of damselflies from the northeastern US (Virginia northward) and eastern Canada. It should be useful for all of the eastern US. Each species account is a full page and includes: life history, range map, flight dates, identification tips, detailed illustrations of both sexes, and smaller diagrams showing anatomic details. There is an introduction to damselflies with detailed diagrams explaining anatomic terms, and there are two pages of references. The book has superior typography and design.
