Argentinian ants take over (or under) Melbourne, Australia: Ants Form Supercolony Spanning 60 Miles. It seems in Argentina the ants are highly aggressive and territorial, so they kill each other off. In Australia, however, they've lost their aggressive edge, so now they cooperate and as a result build huge supercolonies.
The same thing has happened in Europe, where the largest supercolony in the world (extending over 3700 miles) has formed.
So it begins....
