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
Myrmecia (ant) lack of food during winter and they could be incipient colonies. The division of labour is based on the size of ant, rather than its age, with the larger workers foraging for food or keeping guard outside the nest, while the smaller workers tend to the brood. Their colouration is variable; black combined with red and yellow is a common pattern, and many species have golden-coloured pubescence (hair). Many other species are brightly coloured, which warns predators to avoid them. The formicine ant "Camponotus bendigensis" is similar in appearance to "M. fulvipes", and data suggest "C. bengdigensis" is a batesian
