Gall midges

Aphidoletes sp.
Diptera: Cecidomyiidae

The adult resembles a small mosquito (A). The bright orange larvae are legless and have no distinct head capsule; the front part of the body is tapered (B). The orange elongated eggs are laid on the leaf surface among aphid colonies.

Note: Gall midges are sensitive to broad-spectrum insecticides.

Status

Larvae are predators of aphids and other soft-bodied insects as well as mites; example, Aphidoletes aphidimyza (C). One larva per 20 to 40 aphids is usually sufficient to attain natural control.
