The hatched larvae feed on the pupae. Bird predation is usually evident only in late-instar larvae or on overwintering pupae. Eggs, larvae or as pupae can overwinter within the tree. Birds may feed on larvae, pupae, or adults. Eggs, larvae and pupae develop more quickly in milder conditions. Bee brood, the eggs, larvae, or pupae of honey bees, is edible and highly nutritious. Eggs hatch to become larvae, which grow until they are able to change into pupae. Their diets consist mostly of termite or ant larvae, pupae, and adults. "Calosoma sycophanta" is a beetle that preys upon the gypsy moth larvae and pupae. Mature colonies contain several queens, winged males, workers, eggs, larvae, pre-pupae and pupae. Their diet consists of the larvae, eggs, and pupae of ants and termites. Parasitoid wasp species differ in which host life-stage they attack&colon; eggs, larvae, pupae, or adults. They also gather larvae, pupae and surrounding cells, known as bee brood, for consumption. Coarctate pupae develop inside the larval skin. Snakeflies are holometabolous insects, having a four-stage life cycle with eggs, larvae, pupae and adults.
