A rare species throughout Belgium.
The adults fly from early June till late July, sometimes till August. They are active at dusk and later come to light.
The larva feeds in the flower heads of Picris hieracioides, Centaurea jacae and Sonchus arvensis. Hibernates as a full-grown larva and pupates in a cocoon in the ground.
