Aphaenogaster carolinensis
Carolina Collared Ant
Aphaenogaster carolinensis is a medium-sized ant species in the family Formicidae, first described by Wheeler in 1915. The species is notable for its documented substrate vibration generating behavior, in which workers strike and drag their mandibles against surfaces to produce vibrations. This behavior occurs most frequently during confrontations with non-nestmate conspecifics and does not require the presence of food or territory to be initiated.
