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 ants are unlikely to be invaded by other species, so nest invasions are an unlikely cause of nest vacation. The structural breakdown of a nest and competition with other neighbouring colonies is also unlikely, but a possible factor is the seasonal production of food sources and food competition. The green-head ant is a diurnal species that is active throughout the day, quickly foraging on either the ground or vegetation. They are scavengers, predators and seed-eaters, generally having a broad diet of animal material, insects, small arthropods, honeydew from sap-sucking insects and seeds. The workers usually prey on beetles, moths and
