A rare and local species in Belgium, with a preference for dry and sandy habitats. More observed in the northern part of the country.
During the day, the larva hides under the ground and hibernates as a pupa in a weak cocoon deep under the ground. The species is active during the day and at night. They come to light and sugar.
The adults fly in one generation from May till mid August. In favourable years a partial second generation occurs in late August and September.
The larva lives on various low plants like Cakile maritima, Honkenya peploides, Spergularia rubra and Plantago lanceolata.
Dry and sandy habitats like coastal dunes, moorland etc...
