Local in woodland throughout much of southern England. In Hampshire widespread and fairly common, although the first Isle of Wight record was not until 1996. Wingspan 20-30 mm. There is some variation in extent of the markings, but this species is clearly distinguished from other resident British Tineidae by its large size (MBGBI Vol 2).
