Black-winged damselfly: Calopteryx maculata.  Click to enlarge. Black-Winged Damselfly

Scientific name: Calopteryx maculata (Beauvois)
(Odonata: Calopterygidae)

Facts:The black-winged damselfly can be readily identified since it is the only species that has solid black wings. Males and females differ somewhat in wing coloration with males being darker winged. Naiads or aquatic nymphs of the black-winged damselfly are typically found in flowing streams. Damselflies are effective predators both as naiads and as adults. A wide variety of damselflies occur throughout Texas. Most of these cannot be accurately identified by anyone except damselfly specialists. All damselflies can be distinguished from dragonflies readily since damselflies hold their wings together over their back when at rest. Moreover, damselflies have their front and hind wings very similar in shape and size.
