Attracted by the smell of honeydew, this tiny midge lays its eggs in colonies and the predatory larvae (shown) attack the aphid prey.
In its larval stages, Aphidoletes aphidimyza is a voracious aphid killer. The more aphids present, the more it will consume. Also known as the gall midge, it’s known to feed on some 60 types of aphids. It’s a popular means of aphid control in greenhouses.

Basically night feeders, the larvae hide on the undersides of leaves during the day. In its adult midge stage, the delicate fly feeds on aphid honey dew and deposits eggs in aphid colonies. The larvae take two-three days to hatch and go through three stages over two weeks, feeding on aphids as they go. The predator spends its pupal stage in the ground. The adult emerges in one to two weeks to lay more eggs among the remaining aphids.
