Mainly confined to southern England, with a few records from further north. Not known from Scotland, Ireland or the Channel Islands. A local mining bee but sometimes abundant where found. A western Palaearctic species, the range extending from Britain to the Urals, and central Iberia to Iran.
This species is not regarded as being scarce or threatened.
Particularly associated with calcareous grassland; occasionally open woodland on chalk, wooded heathland and fenland.
