Excavator: Ground. Details unknown, but the phenology suggests that the species may be primitively eusocial (Pesenko, Banaszak et al., 2000). Blagoveschenskaya (1963) observed a huge nesting aggregation covering an area of 360 000 square metres, and containing an estimated 4.68 million nests.
The nest entrance is surrounded by a high tumulus of spoil, about 3cm in height.
