Habits: The moth visits flowers after dark and is attracted to sugar and light.

Foodplant: The polyphagous larva feeds nocturnally on Common Nettle, Foxglove, Red Clover, Broad-leaved Dock and other herbaceous plants. Then in the spring it feeds on woody plants such as Hawthorn, sallows, Bramble, Broom and Blackthorn. It hides in loose soil or leaf litter during the day. Pupation takes place in an earthen cocoon under the soil.

On the European mainland it has also been recorded feeding on bedstraw, sorrels and Heather.
