Probably oligolectic: In Germany the species is perhaps mainly oligolectic on Brassicaceae, females visiting Brassica napus, Brassica rapa, Sinapis arvensis, Raphanus raphanistrum, Cardaria draba, Capsella bursa-pastoris and Berteroa incana, but females may also collect pollen from Apiaceae (Westrich, 1989).
Tomozei (2014) citing others states the species visits Isatis tinctoria, Arabidopsis thaliana, Capsella bursa pastoris, Brassica, Berteroa incana, Alyssum tortuosum, Alyssum desertorum, Raphanus (Brassicaceae); Anethum graveolens, Daucus (Apiaceae); Veronica chamaedrys (Plantaginaceae); Salix (Salicaceae) and Taraxacum officinale (Asteraceae) (Dylewska 1987, Osytshnjuk 1977).
Dardón Peralta (2010), citing others, states that the species appears to be polylectic and visits Apiaceae, Berteroa incana, Brassica sp., Capsella bursa-pastoris (Brassicaceae); Salix (Salicaceae); Taraxacum officinale (Asteraceae); Veronica chamaedrys (Plantaginaceae).
