A fairly common species throughout most of the British Isles, occupying woodland, parks and gardens.
The adult moths are on the wing in June and July. They can be found during the day by searching tree trunks but are more often encountered at light.
The larva feeds in a spinning on a leaf of elm (Ulmus spp), from which it is easily beaten. Pupa undescribed.
