A very rare and declining species. The species used to occur in dry heathlands in the Kempen, but seem to be extinct (about 2000) in Flanders nowadays. In the southern provinces, regular observations in the Famenne, Viroin and the extreme south.
The larva hibernates.
The adults are attracted to light, sugar and the flowers of e.g. Calluna vulgaris.
The adults are on the wing in the second half of August till mid September.
