A very local and rare species in Belgium.
The larvae live in a loose spinningon the leaves, close to the central shoot, later they move to the central rosette of the foodplant. 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.
Open places in forests, heathlands.
