Driver ants (genus Dorylus), native primarily to central and east Africa, are nomadic army ants famous for their massive, blind raiding swarms and highly aggressive behavior. Colonies can exceed 20 million individuals, making them some of the largest single-family societies on Earth.
Anatomy & Hierarchy
The Queen: Up to 3-5 cm long, they are the largest ants on Earth. They can lay over 1,000,000 eggs per month.
Soldiers: Feature enormous, hooked jaws used to pierce prey and defend columns. Their bite is so strong, indigenous tribes in Africa historically used them as natural, biodegradable medical stitches by letting them clamp shut over a wound.
Workers: Vary in size (polymorphic). They are entirely blind and navigate using chemical trails.
Males: Nicknamed "sausage flies," they are giant, winged ants with bloated abdomens. They leave the nest to mate but are guided back to queens by following the workers' scent trails.
Behavior & Migration
Nomadic Lifestyle: They do not build permanent nests. Instead, the colony moves continuously, creating temporary living structures (bivouacs) out of their own interlaced bodies.
Swarm Raids: Millions of workers march in sweeping, highly organized columns, stripping the terrain of insects, spiders, and even larger vertebrates that cannot escape.Bridge & Raft Building: To overcome obstacles, rivers, or uneven terrain, they form living bridges and rafts using their own bodies.
