One of the biggest feral supercolonies in the world is taking over Melbourne. The invaders are Argentine Ants, and they’ve formed a mafia that has systematically wrestled control of the suburbs from the native ants over the last 50 years. We find out how they managed to stage such a massive coup and what effects they are having on the native ecosystems.
Most commonly, ants from different nests exhibit aggression toward each other. However, some ants exhibit the phenomenon called unicoloniality, where worker ants freely mix between different nests. A group of nests where ants do not exhibit mutual aggression is known as a supercolony - this form of organization is known as supercoloniality, and ants from different supercolonies of the same species do exhibit mutual aggression. Populations in supercolonies do not necessarily span a contiguous area. [2]
