Polylectic; pollen sources include Lamiaceae, Fabaceae and Boraginaceae (e.g. Echium) (A. Müller, unpublished, based on 12 pollen samples from 10 different localities). Males were observed to patrol flowers of Stachys recta (Gogala, 2009).
Banaszak & Romasenko (1998) list Fabaceae and Lamiaceae as forage sources. Gogala (2009) reports collecting a female at Stachys subcrenata and Stachys recta (Lamiaceae).
