Nationally scarce (Nb) in woodland and on heaths throughout much of Britain, except in northern Scotland. In Hampshire and on the Isle of Wight recorded in small numbers from all three vice-counties, but flies early in the year and is easily overlooked. There have been no recent records from the Isle of Wight. Wingspan 14-16 mm. The comparatively long and narrow forewings are characteristic of this species [Bradley]. Larva feeds within bark of Oak, forming galls, over-wintering as a pupa in a cocoon.
