Excavator: Ground. R.C.L. Perkins (1917d) was the first to discover that individual nests are clustered together, all the females of such an aggregation sharing a single entrance burrow. Nests are usually excavated in a steep bank or hillock, but I have also observed specimens flying deep into a rabbit burrow, somewhere within which they clearly had their nest.
Osyschnjuk et al. (2008) state that it nests in the soil solitary or in small aggregations. No mention is made of communal nesting behaviour
