Also known as the driver, safari or army ant, this African species if the only insect known to attack and devour humans, although this happens only very rarely. Siafu ants have very large, sharp jaws and venomous stings, which they use to subdue small animals such as lizards, worms and other insects. However, there have been reports of cows, goats and other domestic animals that were tied to trees or poles by their owners, and, unable to get out of the way, were killed by the Siafu ants. Wild animals avoid ant armies on the move, and some naturalists have claimed that even lions and elephants flee away from them.There have been reports of attacks on people who couldn’t run away on time, such as unattended babies, sleeping or injured people and at least one drunken man. Also, one tourist that was reported as missing in Tanzania was later found to have been killed by Siafu ants. It is said that these larger victims may not die of envenomation after being stung, but rather of asphyxia, since the attacking ants will go into any body orifice and crawl into the lungs.
