Description and notes

This is a medium-sized cleptoparasitic bee which is yellow and black, although some females may be red, yellow and black. The bees can be very obvious on some heathland sites, being more readily found than their hosts (bees of the Andrena denticulata group).

Distribution

Distributed throughout England, Wales and the Isle of Man, although more common in the south. Also recorded from the Isles of Scilly and the Channel Islands. It is local in Europe, where it is considered to be a northern species which becomes scare towards the south of Europe. As with two of its most frequent host species, A. denticulata and A. fuscipes, there is concern over the status of this bee in Germany, it being accorded Red List V (Vulnerable), status.

Status (in Britain only)

This bee is not regarded as being scarce or threatened in Britain.

Habitat

As its hosts have a wide range of habitat types in which they may occur, so N. rufipes is found in a similarly wide range of habitats. However, it is most frequently found on heathlands. There is a population on the calcareous grasslands of Salisbury Plain where the bee is associated with Andrena nitidiuscula

Flight period

Univoltine: July to September

Pollen collected

This is a cleptoparasitic bee and does not collect its own pollen.

Nesting biology

The female bee lays her eggs in provisioned cells inside the underground nest s of its hosts, which are bees of the Andrena denticulata group, and probably A. nitidiuscula (S.P.M. Roberts pers. comm)

Flowers visited

Ragwort (Senecio jacobaea) and heathers (Ericaceae) are very frequently visited, although N. rufipes may be found at a much wider range of flowers than this.

Parasites

None known.
