A common species throughout Belgium, especially in the northern part.
The adults, resembling a bird dropping, fly from early June till the end of September. They are active from dusk and later come to light.
The larva lives in a spun shoot or a folded leaf on Salix alba, less frequently on other species of Salix, Populus tremula or P. nigra. Pupation takes place in the larval habitation.
