Argentine ant concrete walls, in spaces between boards and timbers, even among belongings in human dwellings. In natural areas, they generally nest shallowly in loose leaf litter or beneath small stones, due to their poor ability to dig deeper nests. However, if a deeper nesting ant species abandons their nest, Argentine ant colonies will readily take over the space. Austrian entomologist Gustav L. Mayr identified the first specimens of "Hypoclinea humilis" in the vicinity of Buenos Aires, Argentina in 1866. This species was shortly transferred to the genus "Iridomyrmex", and finally to "Linepithema" in the early 1990s. The native range of Argentine

Despite their dominance among ants, a number of animals are known to prey on meat ants. The short-beaked echidna ("Tachyglossus aculeatus") is a prominent predator of the meat ant, mostly due to the high fat levels (up to 47%) in virgin queens. These queens can almost contain 47% fat, and when no queens are available after an attack, an echidna may stop attacking the nest. However, these ants are normally consumed either in low numbers or avoided entirely.
