A very rare species throughout Belgium.
Free living instars construct three consecutive cones from a leaf lobe. Pupation on the underside of a leaf under a white silken cocoon, most of the time near the last cone. The species hibernates in the adult stage. The adults come sparsely to light.
The adults fly in two generations a year: during July and early August and again from September till May.
