Formerly recorded from East and West Kent (St. Margaret's Bay, Dover, Upper Halling) and East Sussex (Eastbourne, Falmer, Litlington, Seaford, Ovendean). There are unconfirmed reports from East Kent (Rochester (Malloch, 1904)), the Isle of Wight (Ventnor (R.C. Bradley in Wainwright, 1903)) and Dorset (Portland (J.C. Dale in F. Smith, 1848)). Unconfirmed literature records are not shown on the map. After an interval of at least fifty years, the species was rediscovered in East Sussex by S.J. Falk in 2003.
In mainland Europe the range extends from southern Sweden (Gotland) east to the Volga. In southern Europe it occurs in isolated pockets, in southern Italy and further east, from St. Petersburg to Azerbaijan (Ebmer, 1988).
