A very rare species throughout Belgium, most observations are from the east. Outside this area are vagrants.
The larva feeds mainly at night.
Hibernates as a small larva. Pupates in moss or plant debris on the surface of the soil, without a cocoon. They come especially to sugar in numbers and also to light, usually late at night.
The adults fly in one generation a year: from mid June till early September.
