A rare species in many parts of Belgium. Most of the observations are along the coast, where in some places it is not so rare. In the other parts of the country, observed mostly as singletons.
The larva feeds on the roots of several grasses. Hibernates as a larva and pupates underground. The adults come to light and sugar.
The adults fly in one generation: onwards from mid May till mid August.
