Excavator: Ground. In an Isle of Wight woodland site I discovered an extensive nesting aggregation in a steep and largely unvegetated bank.
Considered to be a eusocial species, with a brood of workers which cannot be distinguished from thee gyne (Westrich, 1989). Social behaviour requires further investigation.
Ebmer (1971) states that the species is often found in large colonies (aggregations) in the banks of clay pits.
