Status (in Britain only)
This bee is not regarded as being scarce or threatened.
Woodland, heaths, moors and coastal dunes. Rarely abundant.
Univoltine; mid May to mid July, exceptionally early August.
Polylectic. Chambers (1968) lists the following as pollen sources: a buttercup (Ranunculus sp.), cinquefoil (Potentilla sp.), common rock-rose (Helianthemum nummularium), dewberry (Rubus caesius), mustard (Brassica sp.), raspberry (Rubus idaeus), rose (Rosa sp.), rough chervil (Chaerophyllum temulum), sheep's sorrel (Rumex acetosella), speedwell (Veronica sp.) and winter-cress (Barbarea vulgaris).
The species is reported to nest solitarily (Kocourek, 1966; Dylewska, 1987; Westrich, 1989). However, R.C.L. Perkins (1919) found a small aggregation of about a dozen burrows placed close together.
In addition to the forage species listed above, the bee has also been reported to visit bilberry (Vaccinium sp.), hawthorn (Crataegus sp.), plum (Prunus sp.), water-dropwort (Oenanthe sp.), wood spurge (Euphorbia amygdaloides) and yellow pimpernel (Lysimachia nemorum).
