Description and notes

Distribution

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.

Status (in Britain only)

This species is not regarded as being scarce or threatened.

Habitat

Particularly associated with calcareous grassland; occasionally open woodland on chalk, wooded heathland and fenland.

Flight period

Females from mid April to late September; males early July to September.

Pollen collected

The bee has been observed collecting dandelion (Taraxacum species) pollen (pers. obs.), but other flowers are doubtless utilised. Polylectic in Germany, foraging from species in the families Apiaceae, Asteraceae, Brassicaceae, Caryophyllaceae, Cornaceae, Ranunculaceae, Rosaceae and Salicaceae (Westrich 1989).

Nesting biology

Nesting habits are apparently largely unknown. In Germany, the species is stated to be "solitary" (i.e. non-social) (Westrich 1989).

Flowers visited

Lesser celandine (Ranunculus ficaria), broom (Cytisus scoparius), plum (Prunus domestica), wild parsnip (Pastinaca sativa), wild carrot (Daucus carota), willow (Salix species), speedwell (Veronica species), guelder-rose (Viburnum opulus), tormentil (Potentilla erecta) and ragwort (Senecio species).
