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
Saharan silver ant Saharan silver ant The Saharan silver ant (Cataglyphis bombycina) is a type of ant that lives in the Sahara Desert. Largely due to the extreme high temperatures of their habitat, but also due to the threat of predators, the ants are active outside their nest for only about ten minutes per day. The twin pressures of predation and temperature restrict their above-ground activity to within a narrow temperature band between that at which predatory lizards cease activity and the ants' own upper threshold. The ants often traverse midday temperatures around to scavenge corpses of heat-stricken animals. To cope with such
