Aphidius ervi attack many species of larger aphids such as the green peach aphid and brassica aphids.
A relatively large wasp (twice the size of Aphidius colemani) with a black, slender body with brown legs and long antennae. The female wasp injects an egg in the aphid with her ovipositor. Hatched larvae eat the aphid from the inside leading to the formation of a a golden-yellowish-brown mummy. Finally, a new adult parasitic wasp leaves the mummy through a round hole.
