Attenborough's Ant Mountain

Sir David Attenborough is our guide through the mysterious realm of ants in this epic tale of two cities. Like any city, they're made up of vast social networks and transport infrastructures, to keep the inhabitants informed and fed. But unlike our urban jungles, these cities are made and run by – wood ants. On the one hand, there is a super-colony over one billion strong – one of the largest animal societies on Earth. Life there is based on cooperation and harmony. On the other hand, we see a single mound city where ants of the same species are always waging wars on neighbouring colonies. Tens of thousands of ants are killed in these conflicts each year.
