A rare but widespread species in Belgium. Most observations in the northern part of the country.
Hibernates as a pupa, in a cocoon among living reed foliage or debris on or near the ground.
The adults are active from dusk onwards and later come to light.
The adults fly in two generations a year; from April till mid September. Very occasionally a partial third generation occurs in October.
The larva lives mainly on Phragmites australis but also on other plants of wet habitats like: Lysimachia vulgaris, Rumex hydrolapathum, Cladium mariscus, Carex paniculata and Salix.
