A rather rare species throughout Belgium. Mostly seen as larvae, rarely seen as imago.
Wingspan: 45–50 mm.
Sometimes many caterpillars on the same plant eating all plant tissues.Hibernates as a pupa in a solid cocoon in the sand, sometimes for several years. The adults come sparsely to light.
The adults fly in one generation a year: from late April till begin July.
The larva lives on Verbascum, Scrophularia or Buddleja.
