Polylectic with a preference for nototribic flowers (Lamiaceae, Antirrhineae) and Fabaceae. The only pollen sample available so far consists of pollen of Fabaceae (A. Müller, unpublished).; additional pollen sources include Cichorioideae (Asteraceae). (A. Müller, unpublished, based on 8 pollen samples from 7 different localities).
The females possess a specialized pilosity on clypeus and frons to remove pollen from nototribic anthers (A. Müller, unpublished).
