A very local and rare species in Belgium. Distribution insufficiently known due to similarity with other species of the family.
The larvae live in a loose spinning on the leaves, close to the central shoot, later they move to the central rosette of the food plant.
Pupation in this rosette or on the underside of a leaf.
One long generation a year, perhaps two hard to distinguish generations: from May till August.
Monophagous on Hieracium pilosellae.
Open places in forests, heathlands.
