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
Green-head ant they prefer. This suggests that the cost of moving to a suitable nesting site outweighs the benefits of moving to a larger rock. A large expenditure of energy is required for a move: scouts must first find a suitable site, brood must be transported safely, and the colony is exposed to an increased risk of predation. Nest abandonment by the green-head ant varies, but peaks during summer. Like other temperate species, activity in colonies is greatly reduced during the colder months, which may be the reason there is a high proportion of nest abandonment during summer. Nests abandoned by green-head
