Excavator: Ground Nests in burrows it finds in the ground (Westrich, 1989).
Peeters, Raemakers & Smit (1999) suggest that the species uses old nest cells of wasps and bees.
Benoist (1959) states that the species is [often] a stem nester, and will construct its nests in Rubus stems, canes and in Phragmites stems, also in the soil [cited in Ornosa & Ortiz-Sánchez, 2004]
