A rather rare species throughout Belgium, could be in some places locally fairly common. Mostly found as larvae.
Hibernates as a pupa in a strong cocoon in the soil, sometimes for several years. The adults come sparsely to light. More seen as larva than as imago.
The adults fly from beginning of April till end of June in one generation.
