The moths are univoltine and visit the flowers of sallows, usually high up. In some years, they can be numerous and in other years, scarce or absent. The females lay their eggs on the catkins of sallows. The case is an elongate-oval shape with each half made of several, roughly crescentic pieces of dead sallow leaves. The larvae feed from May onwards and can overwinter two or three times. Pupation takes place within the case in March.
