The only pollen sample available so far consists of pollen of Antirrhineae (Plantaginaceae) and Fabaceae (A. Müller, unpublished). The females are equipped with a specialized pilosity on the clypeus composed of curved bristles, which are certainly used to comb pollen from the nototribic anthers of Antirrhineae and probably Lamiaceae (A. Müller, unpublished).
