Stunning close-up videos of common dragonflies and damselflies. Video showing behavior and a variety of angles is a great supplement to a field guide. 50 widespread eastern species are covered in a one-hour DVD. Sequences show life cycle and habitats, so it is more than a field guide.
Coverage of North Carolina species is particularly good, since one of the authors is based there. The footage of damselflies is especially welcome, since there is no in-print field guide for the eastern US.
My only wish is for a booklet to accompany it, and subtitles. (There are explanatory notes included in the DVD.) My copy had one minor glitch that only showed up on one DVD player, but not on another. This was not a fatal flaw, only annoying. (I have seen similar problems on other commercial DVD's.)
Full discosure note:
I know Greg Dodge, and made some very minor contributions to this DVD.
