It is found from Fennoscandia to the Pyrenees, Italy, and Bulgaria, and from Great Britain to central and southern Russia, further east to Japan. The wingspan is 11–13 mm. Adults are on wing from July to August. The larvae feed on Artemisia vulgaris.

Normally, the larvae feed on developing fruits, but might stray to the leaves.
