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
Meat ant to gain access to water or where water has been spilt, either if the site is nearby their nest or far away. Despite their dominance among ants, a number of animals are known to prey on meat ants. The short-beaked echidna ("Tachyglossus aculeatus") is a prominent predator of the meat ant, mostly due to the high fat levels (up to 47%) in virgin queens. These queens can almost contain 47% fat, and when no queens are available after an attack, an echidna may stop attacking the nest. However, these ants are normally consumed either in low numbers or avoided entirely.
