A sophisticated underground ant city once populated by millions of insects has been discovered by a team of scientists.
The abandoned megalopolis, which features vast subterranean highways, paths and gardens, was found buried beneath the earth in Brazil.
It is thought to have housed one of the biggest ant colonies in the world. But no one is sure when the leafcutter species left and what caused their demise.
Experts poured ten tonnes of concrete into holes on the surface – which served as air conditioning ducts for the ants – to expose the tunnels by solidifying in the space.
It took ten days to pour the material down the labyrinth of channels, which covered an area of 500sq ft and extended to 26ft below the surface..
After a month, scientists, led by professor Luis Forgi, began digging and revealed the incredible city described as the ‘ant equivalent of the Great Wall of China’.
The community of ants – described as a ‘superorganism’ because of the way they coordinated themselves – carried out a Herculean task building their giant home.
