This ant, formerly known as Paratrechina faisonensis, is poorly studied. Watch it carefully. Photo by B. Guenard who, after taking this picture, mysteriously disappeared into an ant colony where he lived for seven long years. Guenard, upon returning to the realm of humans is said to have felt that the hardest part about living below ground was the lack of pillows. "Ants," he offered, "simply don't care where they rest their heads."
