Description and notes

The female of this species is one of the more attractive and distinctive bees which occur in Britain, the extremely long, golden pollen-collecting hairs on the hind tibiae being particularly notable. D. hirtipes is the only member of its genus which occurs in Britain.

Distribution

Southern England and Wales, northwards to Merionethshire and Norfolk; also recorded from Guernsey and Jersey. Widely distributed in Europe, from southern Finland south to Spain and the Canary Islands, and east to Turkey, Ukraine and Armenia. It occurs in North Africa including Egypt.

Status (in Britain only)

A Nationally Notable (Nb) species.

Habitat

Sandy soils, particularly on heathlands and coastal dunes.

Flight period

Univoltine; late June to the end of August or the beginning of September.

Pollen collected

Oligolectic on Asteraceae; plants visited include common ragwort (Senecio jacobaea), fleabane (Pulicaria dysenterica), creeping thistle (Cirsium arvense), cat's-ear (Hypochoeris radicata), hawkbit (Leontodon hispidus), perennial sow-thistle (Sonchus arvensis) and smooth hawk's-beard (Crepis capillaris), though further confirmation of these being forage species is required.

Nesting biology

Females mainly excavate their nests in sandy, sparsely vegetated, level soil. Some sites contain nest aggregations of great extent. The main burrow is very long (8-60 cm) and is excavated at an oblique angle, resulting in a ‘fan’ of spoil to one side of the entrance. Cells are built at the ends of laterals which arise from the distal portion of the main burrow. In Denmark (and possibly in Britain), nest excavation usually takes place in the afternoon, females rarely leaving their burrows after mid-day or early afternoon (Lind, 1968). During excavation the hind tibial scopa is used as a brush to clear soil from the burrow entrance (Saunders, 1908; G R Else, pers. obs.). Nests are described by Müller (1884), Malyshev (1927) and Lind (1968). The early stages have been described by Müller (1884) and Rozen & McGinley (1974).

Flowers visited

This bee is especially associated with yellow Asteraceae flowers. A record of a visit to an onion (Allium sp.) probably refers to a nectar source. Flower visits are more oft en observed in the morning as most of the blooms that both sexes visit tend to close from late morning onwards.

Parasites

Sarcophagid flies in the genus Miltogramma seem to be important parasitoids in the nests of this bee (Müller, 1884; Gardner, 1901; Pape, 1987).
