The dragonflies have a very voluminous head, the eyes made up of about 50,000 ommatidia and relatively short antennae; the two pairs of wings, almost equal, are elongated and membranous, and sometimes in bright colors, and allow a quick and safe flight. The abdomen is relatively long and thin, composed of eleven segments. The legs are inserted anteriorly on the body and are rarely used for walking. With their wings they can reach a speed of 50 km per hour..
