A very rare and local species throughout Belgium, mainly distributed on dry sandy soils. More observed in the Kempen, mostly as singletons, but sometimes in higher numbers.
It's a declining species everywhere in Europe.
The larva is active during the night.
Pupation in a small hole underground. In the summer during extreme warm and dry periods, the adults are inactive and holding a rest period, called aestivation. They come to light and sugar.
The adults fly in one long generation: from end of May till the end of September.
