The larvae feed on Aster amellus, Succisa pratensis, Gnaphalium and Hieracium species. On Aster amellus, they mine the leaves. The mine has the form of a full depth broad corridor or elongate blotch.

After hibernation, the larva leaves the mine and spins together some leaves from which it continues feeding. Larvae can be found from September to May.
