Many workers from Niapu and Garamba (Lang and Chapin). Those from Niapu "came in thousands to the body of a dead bird. They had their nest in a cleared place about thirty yards away. The following day they had moved their nest to the base of a decomposed root but towards evening had returned to their original nest. This extended about two feet below the surface of the soil." At Garamba the species was found "making crater nests about three inches high about the stalks of grasses in a dry plain (savannah) with few trees." Thirteen specimens from this locality were taken from the stomach of a toad (Bufo regularis).
