Polylectic: Gogala (2011) lists Asparagus officinalis (Asparagaceae) as pollen source in Slovenia
Tomozei (2014) citing others, states that the species is polylectic, in that it prefers to forage upon a wide range of flowering plants species, including flowers of Taraxacum, Tussilago (Asteraceae); Brassica rapa (Brassicaceae); Cytisus (Fabaceae); Rumex acetosella (Polygonaceae); Rhamnus cathartica (Rhamnaceae); Salix (Salicaceae); Anemone nemorosa (Ranunculaceae); Fragaria vesca (Rosaceae) and Veronica chamaedrys (Plantaginaceae) (Kocourek 1966).
