Lectic status unknown. The females of H. mazzuccoi possess a specialized pilosity on clypeus and frons composed of apically twisted bristles (A. Müller, unpublished). Similar facial combs occur in several unrelated bee taxa where they serve to remove pollen from the nototribic anthers of Lamiaceae and Antirrhineae (Houston, 2000; Müller, 1996; Thorp, 2000). Thus, flowers of the Lamiaceae may be important pollen sources for H. mazzuccoi. Flower records: Males were observed to patrol flowers of Lotus (Gogala, 2009b).
