A rather rare species throughout Belgium.
The adults fly from end May till the beginning of August. They are active in late evening and later come to light.
The larva lives on the seeds of Arctium lappa, possibly also on A. minus. It hibernates full-fed from October in a cocoon on the ground, or, occasionally, in the see-head. Pupation in the cocoon.
