Dragonfly Nymphs are predators and feed mostly on other insects in the water. They are known cannibals. Some of the larger species feed on small fish and tadpoles. They catch their food with a toothed lower lip (labium) that is usually folded under the head. When prey comes near, the nymph will shoot out its lower lip to grab it, faster than most prey can react. The lip is then pulled back to the waiting mouth and feeding begins.
Much of a dragonfly's life is spent in the larval stage where it moults six to 15 times. The nymph crawls out of the water and moults one last time, emerging as an adult with functional wings. Dragonflies and damselflies do not go through a pupal stage to become an adult.
