Army Ants

What eats every animal in its path, raids other ant colonies, and migrates to find more food? An army ant colony!

Army ants are amazing creatures! Not only have they founded nests, developed a social hierarchy, and migrated to other areas, but they also have a very interesting life cycle and colony structure.

Army ant colonies consist of the queen, the queen’s brood (her eggs), soldiers, and the workers. Army ants are nomadic, making temporary nests as they travel. The nest is made up of the army ants themselves. They form walls and fasten onto each other by using their mandibles (jaws) and their claws. This way, they can hang from a log or another surface while the nest encloses the queen and her brood.

Army ants are referred to as bivouacs — a cluster of ants. Their nests have chambers and corridors where they can bring in prey and transport eggs are being transported to other areas in the nest.

Because of their large colony size, army ants migrate in order to find food. They may raid other colonies and capture slaves. During the nomadic phase, army ants march at night and stop to camp in daylight. The colony starts its stationary phase when the need for food decreases. Then they make temporary nests and change them every day. Each of these rampages lasts for about 17 days. Some say that army ants may have a collective intelligence

Army ants kill and eat up to 100,000 animals in a day. Together they can kill lizards, snakes, chickens, pigs, goats, scorpions, and many other animals. They also climb trees and eat birds plus insects that may live in trees.

Egg – larva – pupa – adult

Egg:

The eggs are microscopic and white or yellowish in color.

Larva:

Larvae do not have eyes or legs. They build a cocoon around themselves.

Pupa:

The pupa is a relatively non-mobile stage.

Adult:

When an individual leaves its cocoon, it is now an adult ant and belongs to a caste.
