It has been recorded from seven different and widely scattered sites in the UK, and it seems it has disappeared from four of these. In England there are three recorded sites, in Cheshire (from where it has not been seen for over a century), Yorkshire (not seen in recent years) and Northumberland, which is the only current site in England. The only known Welsh site is in Ceredigion (Cardiganshire), and it has not been seen here since 1967. In Scotland, it is recorded in Aberdeenshire, Dumfriesshire and Abernethy Forest in Inverness-shire but, here too, it has disappeared from two sites. Outside of the UK, it has an extensive range across the lowlands of the northern hemisphere, although it is confined to the more northerly latitudes.
