Polylectic with a preference for Fabaceae (e.g. Lotus creticus, Medicago marina), other pollen sources include Asteraceae, Brassicaceae, Boraginaceae (e.g. Echium) and Oxalidaceae (e.g. Oxalis pes-caprae) (Haeseler, 1997, 2008; A. Müller, unpublished, based on 16 pollen samples from 6 different localities).
The females are equipped with a specialized pilosity on clypeus and frons composed of curved bristles, which are used to comb pollen from the nototribic anthers of Lamiaceae and Antirrhineae (Müller, 1996b; Müller et al., 1997).
