This is a very similar bee to the common Sphecodes geoffrellus (Kirby) and confusion, particularly in the female, most probably occurs.
This bee, though scarce, is most frequent in south-east and eastern England. It is not known from Wales, Scotland or Ireland.
Abroad, a widespread species from Finland and Denmark, east to Samos and southern Turkey, Sultan Daglari; south to North Africa (A W Ebmer, pers. comm.). In central Europe it can be locally common though sporadic (S Roberts, pers. comm.).
