The skin splits at a weak spot behind the head and the adult dragonfly crawls out of its old larval skin, waits for the sun to rise, pumps up its wings and flies off to feed on midges and flies. Dragonflies do not normally bite or sting humans, although they will bite in order to escape, if grasped by the abdomen.
