The Global Domination of Argentine Ants

Apparently ants--normally territorial--form super colonies that may stretch hundreds of miles. Members of the super colonies refuse to fight one another. Well, there is a mega-colony from Argentina that has spread throughout the world, and regardless of which country they live in, the Argentine ants seem to be part of the same colony and tolerate each other, refusing to fight. Weird.

A single mega-colony of ants has colonised much of the world, scientists have discovered.

Argentine ants living in vast numbers across Europe, the US and Japan belong to the same inter-related colony, and will refuse to fight one another.

The colony may be the largest of its type ever known for any insect species, and could rival humans in the scale of its world domination.
