A very rare and declining species in Belgium, in the past only known from the coast and the southern part of LX.
Few observations since 2000, all in the extreme west of WV.
Hibernates as a larva and pupates in a cocoon among lichens.
They are attracted to light, otherwise seldom seen.
The adults fly in one generation a year: from beginning of June till early August.
The larva lives on various species of lichens on tree trunks, branches and stems of woody plants and sometimes on walls and rocky surfaces.
