A parasitic wasp that attacks several species of aphids. Used mostly in greenhouses producing vegetables and ornamentals. Adult wasps are black 2-3 mm long with long antennae and narrow mid drifts. Adult females lay eggs from their abdomen by quickly curling their abdomen and puncturing an aphid simultaneously with their ovipositor. The egg, once inside the aphid, will hatch into a larva and consume the aphid. 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.
