Nationally scarce (Na) in parts of southern England, southern Scotland and Perthshire, probably overlooked elsewhere. In Hampshire known mainly from a handful of sites in the south of the county, including Havant Thicket and Emer Bog, and first reported in VC12 at Silchester Common in 2019. Not recorded from the Isle of Wight to date. Male unknown, female wingless. The adult moths are seen occasionally, but most records are of larval cases.
