A local and very rare species in Belgium.
The larva mines the leaves of their host plant. The mine consists of a short, irregular, full depth coridor, which is always located at the leaf margin and generally in the tip of the leaf, the frass broadly scattered. The older larva lives freely on the leaf.

The adults fly in two generations in May and June and again during August and September.
