A very rare and local species in Belgium, mainly observed in the southern part of the country.
The adults fly in June and July. They are active at dusk and later come to light.
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.
