The male Beautiful Demoiselle dragonfly has a metallic blue thorax and abdomen and purple-brown wings; the female has a green thorax and brownish wings. They capture insects with their legs while in flight or snatch them off vegetation. So specialized have their legs become that they can only perch on or cling to vegetation; they are unable to walk on a horizontal surface. An additional handicap in walking is the length of the body extending behind the legs.
