Aphidius colemani is a parasitic wasp, less than 1/8 inch long that stings aphids, laying its egg directly inside the aphid host. As many as 200-300 aphids are attacked by each female. During the larval stage, the larva will feed within the body of the aphid. As the larva matures the aphid swells and is killed leaving the aphid mummified and a tan or golden color. The adult parasite chews its way out of the mummy leaving a hole. Once it is able to fly, it will sting more aphids continuing the cycle.
