A very rare and local species in Belgium, mainly known from the Kempen. Outside this area are probably wanderers.
The adults fly in one generation a year; from mid June till mid August. They come to light.
The larva lives on Phragmites australis and on lichens and algae growing on dead wood. Hibernates as a larva and pupates in a thin greyish cocoon inside a stem of reed.
