Polylectic: Surprisingly the British and Irish pollen sources are not known, though the species is considered to be polylectic; the species is particularly associated with Veronica chamaedrys (Plantaginaceae) and Apiaceae, but it also flies to Rorippa sylvestris (Brassicaceae); Rubus, Potentilla, Fragaria, Crataegus (Rosaceae); Sedum (Crassulaceae); Chaerophyllum temulentum, Pimpinella saxifraga, Aegopodium, Oenanthe, Angelica, Pastinaca sativa, Heracleum sphondylium, Daucus (Apiaceae); Euphorbia (Euphorbiaceae); Erica cinerea (Ericaceae); Myosotis (Boraginaceae); Galium (Rubiaceae) and Achillea (Asteraceae).
In Germany, Westrich (1989) reports the species as foraging for pollen from species in the plant families Apiaceae, Asteraceae and Plantaginaceae.
In Finland, the species is reported to visit Aegopodium (Apiaceae)and Saxifraga (Saxifragaceae)(Söderman & Leinonen, 2003).
Tomozei & Radchenko (2015), citing others, states that the species is a generalist, and females visit flowers of Ranunculaceae (Ranunculus), Plantaginaceae (Veronica), Apiaceae (Carum carvi, Aegopodium podagraria, Anthriscus sylvestris); Asteraceae (Taraxacum officinale); Brassicaceae (Isatis tinctoria), Salicaceae (Salix) and Rosaceae (Fragaria vesca) (Osytshnjuk 1977, Dylewska 1987). In western Europe, the females visit flowers of different plants; while in Finland this species is marked on the flowers of 37 species (Elfving 1968).
Dardón Peralta (2010) reports visitation to Thapsia villosa, Carum carvi, Chaerophyllum temulum, Daucus carota, Aegopodium podagraria, Anthriscus sylvestris, Pimpinella saxifraga (Apiaceae); Rorippa sylvestris, Sinapis arvensis, Brassica napus, Cardaria draba (Brassicaceae); Fragaria vesca, Potentilla (Rosaceae); Solidago canadensis, Taraxacum officinale (Asteraceae); Veronica chamaedrys (Plantaginaceae).
