A very rare species in Belgium, nowadays only known from the southern part of our country. A declining species everywhere.
The adults fly in one generation a year; from end of June till half August. They come sparsely to light.
The larva feeds on lichens growing on rocks, stone walls, bushes, fences and gateposts. Hibernation as a larva, pupation in a loose cocoon in crevices.
