Once a very local species in the extreme south of Belgium. Now extinct in our country. Because there are some localized populations in Champagne-Ardenne (France) less than 50 kms from our border, there is always a rare possibility to see a vagrant.

The larva lives on Centaurea, Cirsium arvense, Plantago etc...  It hibernates as a third instar larva.

The adults fly in one generation a year during June and July.
