Meat ant a number of dead or alive animals, including metamorphic crucifix toads, snakes, lizards, and birds. On some occasions, swarms of workers have been found on dead foxes. The meat ant is the only known ant in Australia that feeds on fresh guano. The collection of guano by a nearby meat ant colony shows the opportunistic nature of the species. Observations show that trails of workers in groups of two to four were found collecting the guano under an active bat roost within an abandoned mine and proceeded to return it to the nest. The collection of guano by any Australian
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
