Sulphur knapweed moth

Agapeta zoegana


This moth is used as an agent of biological pest control against noxious knapweeds. The adult moth is bright yellow with areas of brown on its wings. It is about 11 millimeters long. The adult lives for only a few days, during which time the female lays eggs on stems and leaves. The larva, a root miner, moves to the root of the plant and tunnels through the cortex as it feeds. This causes moderate damage to the plant. Flight is from May to August from dusk, and is attracted to light.
