Meat ant some are inquilines and live in the nest commensally. Unused or abandoned areas inside colonies are sometimes occupied by other species of ants and in some cases, termites. Meat ants may deliberately destroy the colonies of the termite "Amitermes laurensis" if competition between the two intensify. Meat ants play an important role in seed dispersal. A meat ant colony is capable of dispersing 334,000 individual bellyache bush seeds per hectare, which shows a strong ant-seed relationship among the two. Meat ants are able to kill poisonous cane toads, an introduced pest, as the toxins exuded by toad, that usually kill
Jack jumper ant or cannot be carried out, known as the nest-site limitation hypothesis. Some queens could even try to return to their nests that they came from after nuptial flight, but end in another nest, in association that nests nearby will be similar to the queens birth nest. The jack jumper ant genome is contained on a single pair of chromosomes (males have just one chromosome, as they are haploid). This is the lowest number known (indeed possible) for any animal, a number shared with the parasitic roundworm "Parascaris equorum univalens". Jack jumper ants are taxonomically discussed as a single biological species
