A rather local species in Belgium, only observed in six provinces.

The larva, when young, lives under a slight web on the underside of a leaf of Centaurea nigra or Verbascum thapsus, making transparent blotches. After hibernation, it lives on the young leaves from a silken gallery at the base of the foodplant. Pupation in a gauzy white cocoon in leaves at the base of the foodplant.

The adults fly in June and July. They are active at dusk and later come to light.
