A very rare and local species in Belgium, not so often recorded.
The adults fly from August till the end of October. They are active from dusk and fly low down amongst the trees and later come to light.
The larva lives on Alnus spp. In early instars in a rolled and puckered leaf, usually those on a terminal shoot. Later on it spins a leaf into a pod. Pupation in the ground in a strong brown cocoon.
