A not so common species throughout Belgium.

The larva lives on Quercus and Betula. Hibernates as a small larva on or near a bud of the food plant. Pupates in a tough, boat-shaped cocoon on the underside of a leaf of the food plant.

The adults fly from late May towards early August in one generation. In favourable years a small partial second generation occurs during September, but it's seldom recorded. They come to light and sugar.
