Aphidoletes aphidimyza
aphid midge
Aphidoletes aphidimyza is a predatory gall midge used worldwide in biological control programs against aphids. Adults are small, delicate, nocturnal flies that feed on aphid honeydew and hide beneath leaves during daylight. The bright orange, slug-like larvae are specialized aphid predators that paralyze prey by injecting venom into leg joints before consuming body contents. The species is commercially mass-produced and distributed as pupae in moist substrate for greenhouse applications.
