A very rare and local species in the northern part of Belgium. Hitherto mainly known from the coastal area and the Scheldt estuary.
The larva hibernates on the food plant or on other plants growing in the grassland vegetation.
The adults are easily disturbed during the day from out of vegetation. On warm days, they fly during daytime. They are attracted to light in small numbers.
The adults fly in one, sometimes two generations a year: from the end of April till the end of August.
