Widely distributed and generally locally common throughout much of the British Isles. It is, however, inexplicably very scarce in Kent (G W Allen, pers. comm.) and Essex (P Harvey, pers. comm.). The range extends north to central Scotland (Renfrew, Midlothian and West Perthshire) and includes the Isle of Man. It is also widespread in Ireland. There are no records of the species from the Channel Islands. In Europe it is mainly found in the north (reaching northern Finland), with only scattered records from further south.
