This would all be set to change however when biologist Mark Wong and colleagues came across a colony of T. rex ants in Singapore while conducting an ant diversity survey in 2016.
It turned out that the ants were most likely nocturnal, thus explaining how they had managed to remain so elusive over the years. The researchers also found that, despite being partial to eating their own kind, the ants seemed to shun other foods such as mites, millipedes and even honey.
When threatened, the insects curled up and played dead until the danger had passed.
"Increasingly, we're finding that many ants which live underground have unique life histories and ecological relationships that are poorly understood," said Wong.
