Americas
Pogonomyrmex barbatus
The American red harvester ant, with one of the most toxic venoms among insects. Never handle bare-handed.
Pogonomyrmex californicus
The California harvester ant, a pleometrotic founder (several queens at the start). Fascinating social behaviour.
Camponotus pennsylvanicus
The black carpenter ant of North America, large, living in dead wood. The North American counterpart of C. ligniperdus.
Atta cephalotes
The other great tropical leafcutter, more jungle-oriented than its cousin A. sexdens. Soldiers with monstrous mandibles.
