Tomozii et al (2016) state that the species is polylectic, in that it prefers to forage upon a wide range of flowering plants species. It prefers Salix, but is able to use the pollen of other plants too (cf. Westrich 1989). The females visit flowers of Asteraceae, Brassicaceae, Rosaceacae, Ranunculaceae, Salicaceae and Euphorbiaceae. It is known as a good pollinator of fruit tree
