Unicoloniality and supercolonies

Most commonly, ants from different nests exhibit aggression towards each other. However, some ants exhibit the phenomenon called unicoloniality: worker ants may freely mix between different nests. Another organization is supercoloniality. The group of nests where ants do not exhibit mutual aggression is called supercolony, while ants from different supercolonies of the same species do exhibit mutual aggression. Populations in supercolonies do not necessarily span a contiguous area. [1]

Until 2000, the largest known ant supercolony was on the Ishikari coast of Hokkaidō, Japan. The colony was estimated to contain 306 million worker ants and one million queen ants living in 45,000 nests interconnected by underground passages over an area of 2.7 km².[2]

In 2000, an enormous supercolony of Argentine ants was found in Southern Europe (report published in 2002). Of 33 ant populations tested along the 6,004 km stretch along the Mediterranean and Atlantic coasts in Southern Europe 30 belonged to one supercolony with estimated millions of nests and billions of workers, interspersed with three populations of another supercolony.[1] The researchers claim that this case of unicoloniality cannot be explained by loss of their genetic diversity due to the genetic bottleneck of the imported ants.

Another supercolony, measuring approximately 100 km wide, was found beneath Melbourne, Australia in 2004.[3]
