Meat ant during territorial disputes to locate them. These alarm signals are created by oscillating the body along the longitudinal axis, which are mostly released when an ant encounters a nest mate. "Cyclotorna monocentra" moths feed on meat ant broods. The larvae of these moths are parasites to leafhoppers and will move to meat ant colonies to complete their development, where they will proceed to consume the brood; the females lay many eggs near ant trails which are close to the leafhoppers tended by ants. Other observations show that the "Iphierga macarista" larvae are scavengers in meat ant nests, while "Sphallomorpha" beetles
Carpenter ant an individual carpenter ant to be recognized as a nestmate, it must, as an adult, go through specific interactions with older members of the nest. This process is also necessary in order for the ant to recognize and distinguish other individuals. If these interactions do not occur in the beginning of adult life, the ant will be unable to be distinguished as a nestmate and unable to distinguish nestmates. Recognition allows for the presence of kin-specific interactions, like kin altruism. Altruistic individuals increase other individuals' fitness at the expense of their own fitness. Carpenter ants perform altruistic actions toward their
