Family: Calopterygidae

Broad-wing Damselflies

These photos supplement pages 67-73 of the Guide to Aquatic Invertebrates of the Upper Midwest. Information on the biology of Calopterygidae can be found on page 70. The gills can sometimes be missing on Calopterygidae (see below), so use the other characters, especially the long antennae, for identification.
