The wingspan is 14–18 mm. Adults are on wing from August to September and again, after overwintering, from May to June.[2]

The larvae feed on Parnassia palustris. They mine the leaves of their host plant. Young larva create a long, irregular gallery in a basal leaf. Older larvae live freely in the hearth of the plant in a white silken tube.[3] The larvae have a light reddish grey body and a brown head. They can be found from June to July.
