Army ant swarm

The army ants have got their names due to their hunting behavior; several thousand ants go hunting for food in a swarm. There are over 200 species of army ants. A colony may have up to half a million ants; one permanently wingless queen, workers (usually females) and males. The queen can lay 3-4 million eggs per month.


These ants are ferocious hunters. The soldier army ants hunt prey. Using their large, strong mandibles they tear apart their prey to carry it back to the colony. Their colonies are huge, with over thousands of ants and therefore they need huge supplies of food. The army ants are always on the move to since they have to forage enough food for the whole colony.

Army ants build temporary nests out of their own bodies called a bivouac. Binding onto each other using hooks and spines on their feet and their mandibles – in this way, the ants form a living nest, complete with walls and tunnels. The tunnels provide shelter and protection for the queen, eggs and the growing larvae and pupae. The workers bring the prey to the queen inside the bivouac.

What do army ants eat?

Army ants kill and consume thousands of prey a day. Mostly they feed on insects and spiders, but they sometimes even kill small mammals. With their team effort they can kill bigger animals like snakes, hens and will raid birds’ nests.
