Like all insects, the dragonfly has a three-part body: a head, a thorax, and a long, thin, segmented abdomen. The dragonfly has 2 large compound eyes that take up most of the head. On the short thorax there are three pairs of jointed legs and two pairs of long, delicate, membranous wings. The dragonfly breathes through spiracles (tiny holes in the abdomen).

Dragonflies typically eat mosquitoes, midges and other small insects like flies, bees, and butterflies. They are usually found around lakes, ponds, streams, and wetlands because their larvae, known as "nymphs", are aquatic.
