Nesting biology-Nesting site: Excavated vertical burrow (ca. 12cm deep) in hard and horizontal soil with 22 brood cells closely grouped together at its end. The brood cells, which are not placed at the end of side burrows but open directly into the main burrow, are spirally arranged around the main burrow with their longitudinal axis being oriented horizontally to 45 degrees downwards.

Nesting biology-Nesting site: Excavated burrow in hard-packed sandy soil. The only nest found so far contained 4 brood cells, which all departed about 3cm below the soil surface from the vertical main burrow, were horizontally oriented and opened directly into the main burrow. Nesting material: The main burrow was lined with a very inconspicuous and thin layer of leaf pulp or possibly leaf sap. The walls of the cells were newly constructed from earth admixed with small leaf pieces after the cell cavity had been excavated from the ground. The cells were completely lined with a thin layer of green leaf pulp and closed with a cap made of earth and small quantities of leaf pieces. (C. Sedivy, C. Praz and A. Müller, personal observation)

Flower preferences: Oligolectic on Zygophyllaceae (A. Müller, unpublished, based on 41 pollen samples from 13 different localities, the pollen content of 4 brood cells from the same nest and field observations).
