A rare species throughout Belgium.
The adults have been observed in July and August. The moths are active in the evening.
The larva lives on the flowers and unripe seeds of Picris hieracioides, P. echioides or Crepis spp. It hibernates full-fed in a cocoon spun amongst detritus on the ground. Pupation inside that cocoon.
