This very rare and local species has not been seen in Belgium for a long time.
The larva is active during the night.
Hibernates as a young larva among lichens and pupates in a cocoon under rocks and stones.
The adults come to light.
The adults fly from mid June till the end of August in one generation.
The larva feeds on lichens, especially on Caloplaca dolomiticola growing on walls and trees.
