A not so common species in most areas of Belgium.
The larva lives in the stem of its food plant. It hibernates in the roots. In spring it mines the young shoots causing them to drop. Pupation on the stem or on a leaf of the food plant.
The adults are active at dusk and come to light.
One generation a year: from July till early September.
