Siafu ants, also known as Driver Ants are one of the most dangerous ants in the world.

Colonies of driver ants can number up to 22 million. Almost daily, swarms embark on raids for food which can be brought back to the nest. Although totally blind, driver ants have no problems getting around. They rely on touch, smell and chemical signals from the abdomen of the leading ants. The swarms can travel at up to 20 meters per hour, stripping all animal life in their path. They are also known to raid the nests of other social insects, although never those of other driver ants. They do not rely on stings to attack; rather they use their large and powerful mandibles to create puncture wounds and tear off sections. Driver ants have a larger impact on their habitat than any other creature and they have to move location at regular intervals to find new feeding grounds. During their nomadic existence they form temporary nests called ‘bivouacs’ made from the living members of the colony, in which they house the developing grubs. Whenever the ants swarm or migrate, they form large highways of workers, bordered by the soldiers, which hang over the action, their mandibles waving, to protect the colony as it moves.
