What Are Army Ants?
The children's song 'The Ants Go Marching' might have been written by someone who was observing army ants. This organized troop of little beasts is known for marching around and taking down everything in its tracks.
Army ants are identified as invertebrates because they have no backbones, and they are grouped with other insects because of their body parts. When they migrate, or move from one place to another, army ants are known for marching by the thousands, over trees and even through houses! But that's just the beginning of what makes them worth knowing about.
What Do Army Ants Look Like?
Looking at ants from far away isn't very threatening. But if you can see one under a microscope, you may think differently. Like other insects, army ants have bodies that are divided into three segments. It also has six legs, two antennae, and a pair of - yes that means two - jaws. Why two jaws? They work like a pair of scissors, which they use to cut, dig, hold things, and even fight! The three segments are called the head, thorax, and abdomen. The antennae are used to help the ants smell, feel, touch, and communicate with other army ants. Some of them also have a stinger, which they rarely use.
How & What Do Army Ants Eat?
You can imagine that anything named after the army has got to be pretty aggressive. Army ants are just that. They are carnivores, which means they eat insects and animals, and they go after their prey by the thousands. They use their powerful jaws to cut and tear through their prey, including other insects, spiders, and even some small animals. As a colony, army ants can attack and eat up to 500,000 prey animals a day. They don't live in the same place for long, since they are always on the move to find more food.
Where Are Army Ants?
Army ants can be found setting up temporary nests throughout parts of the United States, but mostly in tropical areas, including rainforests, swamp forests and more, in South America, Central America, Africa, and Asia. You couldn't miss them if you saw them, because one colony can have up to 24 million ants.
If you did happen to walk up on a colony of army ants, you'd probably see them in a formation called a bivouac. This is a temporary nest that the worker ants build by organizing and binding their bodies together using hooks and spines on their feet and jaws to attach to each other. As they travel, or even sometimes when they're not, they rebuild the bivouac to used it to protect the queen of the colony, who lays up to 30,000 eggs daily, along with the eggs and very young ants.
Army ants are insects that are best known for marching from place to place to get enough food for their colonies. They are carnivorous hunters that can be found in several continents. They use their bodies to make temporary nests called bivouacs.
