Predation: This species has a defense mechanism to combat an attack on the colony by other species of ant, particularly the army ant. This response is evacuation. 15 seconds after the introduction of 100-150 army ants, a stream of workers exits the colony. Eggs, larvae, and even the queen are evacuated from the colony. The evacuation is accomplished with the help of a pheromone that is released as a sort of ‘panic alarm,’ that warns the colony to evacuate (Smith and Haight, 2007: 2; Holldöler and Wilson, 1990: 239).
Known predators: Army Ants: Neivamyrmes nigrescens (Smith and Haight, 2007: 2).
