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
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
