Biology
Pikart et al. (2015) found in aggression experiments that Acromyrmex subterraneus workers were very aggressive to non-nestmate Acromyrmex subterraneus and workers of Acromyrmex subterraneus molestans, Acromyrmex subterraneus brunneus and Acromyrmex niger. Interactions with winged queens of the social parasite Acromyrmex ameliae produced a slightly less aggressive response.
