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 chambers where the population remains during the winter. In the upper areas of the colony, the galleries and shafts only account for 7–10% of nest space. For example, the galleries of excavated colonies occupy whereas the total volume is around . Overall, a nest may dwell extremely deep beneath the soil as excavated nests are as deep as . A diurnal species (active mainly during the day), the meat ant shows minimal interaction with nocturnal ant species when their territories overlap. The meat ant and other members of the "I. purpureus" species group are regarded as a dominant group of
