A very rare species in Belgium, mainly observed in the southern part.
The adults fly from late June towards end of August. They are active from dusk onwards and later come to light. Sometimes disturbed during the day on the food plant.
The larva lives mainly on Senecio and Solidago. Hibernates as pupa in a cocoon in debris, sometimes as long as 2 years.
