Siafu Ant
Siafu ants, also known as driver ants or dorylus, are army ants that are found in east and central Africa. Each colony has more than 20 million ants, with a separate soldier class comprised of ant workers with larger heads and mandibles (similar to pincers). Siafu ants attack aggressively when they are threatened, and when they bite, they tend to hold on, even after their victim dies. These ants are sometimes used as a natural means of pest control, especially when it comes to farming communities who need to prevent insects and rats from destroying their crops.
