11. Adult - Nymph molts their exoskeletons as they grow. As this occurs, they gradually begin to look more and more like an adult. once the nymph has grown to an adult size, they stop molting. Generally, it is in the adult stage where insects develop its wings. An adult’s primary interest is mating.
