A very rare and local species in Belgium.

A mining species of which the larvae live in the stalk and leaves of the food plant. During winter they mine the basal part of the leaves of its hostplant. In spring the overwintered larvae mine higher in the leaf. The larva exits the mine via a hole at the upper side of the leaf.
The adults come to light.
Adults fly from late May through July, with most specimens recorded in June.
