A univoltine species, flying from late March or early April to early June (Westrich and Schwenninger 1997; A. Gogala pers. comm. 2013), however, one female has been recorded from mid-August in Tossa de Mar (Spain), indicating that the species is probably at least partly bivoltine (Warncke 1976).
The only Andrena which invariably has only 2 sub-marginal cells.
