A not so common species throughout Belgium.

The larva lives mainly on Quercus or Betula, but also on other deciduous trees including Ulmus, Corylus and Populus tremulus. Hibernates as a pupa, in a tough boat-shaped cocoon either on the underside of a leaf of the food plant or in a bark crevice.

The adults fly usually in one generation a year; from May till begin of July. In favourite conditions, a smaller second generation occurs from end of July till begin of September. They come to light.
