The wingspan is 9-9.5 mm.[2] Adults are on wing from August to May. Then the larva hibernates outside of the mine in a hibernaculum.

The larvae feed on Lathyrus montanus, Lathyrus niger, Vicia sepium and Vicia pisiformis. They mine the leaves of their host plant. The mine has the form of a large blotch, that may occupy an entire leaflet. During feeding pauses, the larva rests in a silken resting place above the midrib. Pupation takes place outside of the mine.[3]
