This species is known from most European countries, but just four small isolated populations are currently known in the UK; these are in north-east Yorkshire, Northumberland, near Balmoral in Aberdeenshire, and Strathspey. A new subcolony was discovered in Deeside in July 2001 (5). Due to a lack of recent records, the status of an historic population in Roxburghshire is unclear (1).
