Müller, A. (2010), Palaearctic Osmiine Bees, ETH Zürich, http://blogs.ethz.ch/osmiini) The species is said to be a strict oligolege of Fabaceae (Amiet et al., 2004; Banaszak and Romasenko, 2001; Westrich, 1989). Indeed, 21 out of 23 pollen samples analysed so far consist of pure Fabaceae pollen; however, two pollen samples of the subspecies hispanica from the same locality contain large amounts of pollen of Boraginaceae (Echium, Anchusa). Thus, the species might be better classified as polylectic with a strong preference for Fabaceae (A. Müller, unpublished, based on 23 pollen samples from 21 different localities).
