The females collect pollen from flowers of the Brassicaceae, Asteraceae, Salicaceae, Aceraceae, Rosaceae, Rubiaceae, Boraginaceae and Ericaceae families. In Poland, the species has been recorded on flowers of 39 plant species from 17 families, preferably Rosaceae (25%), Saxifragaceae (22%), Brassicaceae (8%), Asteraceae, Berberidaceae, Salicaceae (6-8%) and Ericaceae (5%).
