The Siafu ant, also called driver ant, and dorylus is commonly found in Central and East Africa. When food supplies are short, the siafu ant colony is on the move, a real army comprising 20 million individual ants, devouring everything in their path.
Their scissor-like jaws slice through their unfortunate prey, whilst the powerful dissolving acid that oozes from their mouths ensures that meals can be digested quickly, without ever halting the column’s relentless progress. Large numbers of ants can kill small or immobilized animals and eat the flesh. You can easily avoid them as the colony don’t move very fast, but if they decide to pass through your house it could be a highly dangerous zone, and they’ll definitely attack you if you’re not moving.
These ants bite is severely painful, leaving two puncture wounds when removed. Moreover, removal is very difficult, as the jaws are extremely strong and can lift 5000 times the ant’s body weight (BBC). Such is the strength of their jaws that, in East Africa, they are used as natural, emergency sutures by indigenous tribal peoples to stitch the wound by getting the ants to bite on both sides of the gash, then breaking off the body.
