Argentine ant paralleled only by human society", and had probably been spread and maintained by human travel. They have been extraordinarily successful, in part, because different nests of the introduced Argentine ants seldom attack or compete with each other, unlike most other species of ant. In their introduced range, their genetic makeup is so uniform that individuals from one nest can mingle in a neighboring nest without being attacked. Thus, in most of their introduced range, they form supercolonies. "Some ants have an extraordinary social organization, called unicoloniality, whereby individuals mix freely among physically separated nests. This type of social organization is
Green-head ant seeds they feed on approximately away from their nests in both unburned and burned habitats. In some cases, the seeds of "Adriana quadripartita" are dispersed much farther; the green-head ant accounts for 93% of all ants that collect these seeds and can disperse them as far as . One study shows that the green-head ant, along with "Aphaenogaster longiceps", removed the highest number of seeds and discarded them on top of their nest, with a few remaining several centimetres under the nest. Most seeds dispersed by the green-head ant and "A.longiceps" are eventually eaten by "Pheidole" ants. Since the seeds
