A rare species in Belgium, mainly observed in the northern part.
The adults have been observed in June and July. They are active from late afternoon onwards and later come to light.
The larva feeds from April till early June in an unopened leaf-bud or in spun leaves, especially those of a terminal shoot of Salix spp., especially S. cinerea, S. repens and S. aurita. Pupation takes place in a flimsy cocoon amongst leaf-litter, usually in a fold of a dead leaf.
