Used mostly in greenhouses producing vegetables and ornamentals. Adult wasps are black 4-5 mm long. Adult females lay eggs from their abdomen by quickly curling their abdomen and puncturing an aphid simultaneously with its ovipositor. The egg once inside the aphid will hatch into a larva and consumes the aphid. The larvae when fully grown will cut a slit in the carcass and attaches it to a fixed object. The larvae then pupates (spins a cocoon) inside the dead aphid. The mummified aphid swells into a characteristic round, golden brown mummy. The emerging adult will cut a symmetrical hole at the bottom end to escape from the mummified aphid.

After injecting the aphid with an egg it takes about a week for the mummy to form and then another week for the adult to appear. Each female can lay more than 100 eggs.768
