Andrena lapponica Zetterstedt, 1838

Description and notes

Distribution

Widely distributed throughout Britain, the range reaching northwards to Golspie, East Ross (Speyside) and West Ross (Beinn Eighe). It includes the Isle of Man but not the Channel Islands. Very local in southern England but more widespread further north and on moors in the south-west. In Ireland it is known from Cork, Wicklow, Dublin and Armagh. Often locally common, though its presence is entirely dependent on the occurrence of its main forage plants. A boreo-alpine species in Europe, widespread in Fennoscandia, more sporadic further south, the range there reaching the Pyrenees and the Romanian Carpathians (Dylewska, 1987). The species is also known from Japan (Tadauchi, Hirashima & Matsumura, 1987).

Status (in Britain only)

This bee is not regarded as being scarce or threatened.

Habitat

Open woodland, moors and montane sites. On Cairn Gorm, Easterness, it has occurred at 600 m (pers. obs.).

Flight period

Univoltine; early April to June, occasionally into early July.

Pollen collected

In the British Isles it is mostly associated with bilberry (Vaccinium myrtillus), though in northern Britain it additionally visits cowberry (Vaccinium vitis-idaea). In Cheshire, Neave (1921) observed the species gathering much pollen from rhododendron (Rhododendron ponticum) as well as from bilberry. In Germany, Westrich (1989) reports the species additionally visiting cranberry (Vaccinium oxycoccos) and bog bilberry (Vaccinium uliginosum) and it is probable it may do so in Britain. He also states that in areas where only bilberry is found, the females will exploit other flowers when the prime forage species is over. For example, females have been observed visiting germander speedwell (Veronica chamaedrys) and a dandelion (Taraxacum sp.). This may be important, as on a visit to a Hampshire woodland where A. lapponica occurred, it was observed that virtually all bilberry flowers had been killed by a severe late frost (pers. obs.).

Nesting biology

The nest burrows seem to be widely scattered, rather than in close aggregations. As such they are rarely encountered.

Flowers visited

Bilberry (Vaccinium myrtillus), blackthorn (Prunus spinosa), common dog-violet (Viola riviniana), cowberry (Vaccinium vitis-idaea), dandelion (Taraxacum officinale), gorse (Ulex europaeus), rhododendron (Rhododendron ponticum), thyme (Thymus polytrichus) and willow (Salix spp.).

Parasites

Nomada panzeri Lepeletier is recorded as a cleptoparasite of this species (Perkins, 1919). The conopid fly Myopa buccata (Linnaeus) may be an inquiline of this Andrena as in both West Sussex and central Easterness, M. Edwards and the author have encountered this dipteran flying with this bee in sites where other solitary aculeates were scarce.
