The damselfly nymph is predacious. Usually it lies in wait for other aquatic bugs to get within range and then grabs them with its 'labium' which is modified lower jaw. The nymph will proceed through 10 to 12 instars, or molts, before becoming fully developed and ready to emerge as an adult. With each molt the nymph becomes somewhat darker in color. Finally the nymph will swim towards the shore and crawl into shoreline vegetation. While clinging to this vegetation the nymph's skin breaks along the wing case and out crawls a shortened version of the adult. Before taking flight, the new adult must pump body fluids into its abdomen and wings. Depending on the species, the adult will live for several weeks to several months before mating and dying.
The adult has four wings that fold over the back. The male of the most common variety in the interior is blue while the female is more of a slate color. For the nymph, a fairly large and bulbous head sits on a tubular shaped body. The eyes of the damsel are fairly pronounced but not as large or pronounced as the eyes of a dragonfly nymph. The tail is three feathery looking appendages. The tail is called the "caudal lamellae" and is actually three gills at the end of the abdomen.
