Family Overview
Coenagrionidae

Narrow-winged Damselflies
This is the largest damselfly family, including roughly 90 North American species in 15 genera. Most genera are found in lentic habitats, except Argia, which is usually found in streams among rocks and plants. Nymphs are climbers and stalking predators among plants and roots. Some of the nymphs in this group can be used for fly-fishing, but usually are only useful in slowly moving water. Unlike most damselfly adults, which tend to rest from flight on plants, members of the Coenagrionidae tend to rest on rocks or other exposed surfaces. Interestingly, adult males and females of the same species tend to differ in color.
