A very rare species throughout Belgium, observed in all provinces but nowadays only observed around the coast near the French border and in the extreme south. It was formerly more widespread.
Hibernates as an egg and pupates in the ground. The adults can be seen during the day feeding on different flowers like Echium, Scabiosa, Centaurea and Knautia. They come to light and to sugar.
The adults fly in one generation a year: from mid June till half August.
