Parasitic wasps

Aphids have several natural enemies. The most commons are the lady beetles and parasitic wasps. The female wasp lays eggs into the aphid. The larva develops inside the aphid and consumes the entire body contents. The skin of the parasitized aphid turns crusty and brown, a form called a mumy. The newly merged adult wasp makes a small round emergence hole to exit from the mumy.
