More than just a small mound of dirt, this “abandoned megalopolis, which features vast subterranean highways, paths and gardens, was found buried beneath the earth in Brazil; 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.” Video after the break.

Each insect would have repeatedly carried loads of earth, weighing more times more than the worker, a distance of what would be just over half a mile in human terms. In total, they excavated around 40 tonnes of soil to create the labyrinth, revealed the Nature’s Secret Power documentary, also featuring Dr Bert Holldobler from the Arizona State University.
