A common species throughout Belgium.
The adults fly from early June till late September, but most observations during July and August. They are mainly active at dusk and later come to light.
The larva lives on Salix, and occasionally on Populus. It prefers the catkins of Salix, but also lives between two leaves spun together. Pupation takes place in the larval habitation or between leaf-litter on the ground. The species hibernates in the egg stage.
