Approximately one million ants work together to build a bridge, designed to help the invasion a large nest. The highly organized ants were recorded in Brazil by an electrical engineer, the Francisco Boni.

The Boni explained the use of the bridge by ants, saying: 'For the ants, it is more efficient to follow the path over a bridge that descends and then ascends, but to walk upside down on the wall. Also, walking backwards, they cannot carry large loads”.
