A rather rare species in Belgium, only seen in four provinces. Recent observations mainly in the north and the center of the country.

The larva lives between spun leaves or under a leaf-edge of Betula. It hibernates as an egg.

The adults fly from mid June till September. They use to rest on trunks of birches during the day and come to light.

ID: A very variable species. In fresh specimens, the white coloured labial palps with dark rings, the white head, thorax and tegulae, and the white forewing with blackish markings are diagnostic for this species. About five groups of raised blackish scales are present on the forewings.
