In Hampshire recorded in recent years only from Fleet, previously known from Havant Thicket, Leckford and Stockbridge Down. Not recorded from the Isle of Wight to date. Wingspan male 13-15 mm, female wingless. The adult moths are seen occasionally, but most records are of larval cases. Larva feeds on lichens growing on tree trunks, living within a movable case.
