Polylectic with a preference for small-flowered Lamiaceae (e.g. Teucrium); additional pollen sources include Helianthemum (Cistaceae) (Amiet et al., 2004; Müller, 1996b; A. Müller, unpublished, based on 5 pollen samples from 5 different localities). Baldock et al. (in prep.) report visitation to Santolina chamaecyparissus (Asteraceae) in the Balearic Islands (Spain)
Pollen-collecting females climb the filaments of the stamina of Teucrium montanum, the flowers of which lack an upper lip, until the head is beyond the uppermost anthers; by rapidly seesawing the underside of the abdomen against the anthers, the bees then directly pick up the pollen into the abdominal scopa (Müller, 1996b; Müller et al., 1997).
