Army Ant

One of the most interesting ants of the tropics are the army ants, which march through the rainforest with the sole intent of devouring small creatures within minutes, turning them into carcasses.  The army is like a wolf pack, but with thousands of miniature creatures of prey merging and uniting to form one great living organism.  Army ants´ jaws are so potent, Indians once used them to suture wounds.  The determined insect was held over a cut and its body squeezed so that its jaws intuitively shut, clamping the flesh together.  The body was then pinched off and the wound left to heal.

Another feature is that, unlike most ant species, army ants do not construct permanent nests; an army ant colony moves almost incessantly over the time it exists. All species are members of the true ant family, Formicidae, but several groups have independently evolved the same basic behavioral and ecological syndrome. This syndrome is often referred to as “legionary behavior”, and is an example of convergent evolution.
