A very rare and local species in Belgium, nowadays only known from the southern part.
The adults fly in one generation a year; from mid May towards late August. The males are flying in the early morning and again from afternoon onwards. Both sexes come to light in small numbers.
The larva lives on lichens growing on rocks, shingle and in grassland. Hibernates as a larva. Pupates in a loose -spun cocoon in a crevice near stony places.
