The wingspan is 9–11 mm.[3] The moths fly during the day and can be found on the wing in two generations, between May and August[4]

The larvae feed on bastard-toadflax (Thesium humifusum) and Thesium inophyllon. They initially mine the leaves of their host plant. Young larvae make a small, full depth, irregular corridor mine. Older larvae live free on the host plant. Larvae can be found from April to June and again in July. They are yellow with a shining black head.[5]
