A recent (2009) arrival in Belgium. Nowadays still very rare and only a few observations in different provinces.
The adults fly in two generations a year; onwards from May towards September. They are active during the day and later come to light.
The larva feeds in stalks on various grasses and different species of herbaceous plants including Chenopodium, Rumex acetosella and Polygonum bistorta.
