A very rare and local species in Belgium. Most observations in the Kempen.
Hibernates as a pupa, usually in a broken, but standing, hollow reed stem sealed with silk. The adults come readily to light.
The adults fly from beginning of May till end of June in one generation a year.
The larva lives on Phragmites australis.
