A very rare and local species in Belgium, mainly observed in the southern part of the country.
Native
The larva, when young, lives under a slight web on the underside of a leaf, 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.
They are active at dusk and later come to light.
The adults can be seen from mid-May towards late August, but they fly mainly in June and July.
The larva lives on Centaurea nigra or Verbascum thapsus.
