What Do Army Ants Eat and How They Hunt

What Do Army Ants Eat

Army ants eat almost any small animal they can overpower, focusing on insects, spiders, and other invertebrates. Their raids can also reach bird eggs, nestlings, and even small vertebrates like lizards and frogs when the colony is large enough to overwhelm them.

How Army Ants Hunt and Forage

Army ants hunt in massive, swirling columns called raids. Workers use their strong jaws and chemical signals to flush prey out of leaf litter, soil, and rotting wood. The swarm moves constantly, and the sheer number of workers turns the ground into a moving net that traps almost anything in its path.

What Happens to the Prey

Once caught, prey is dismembered by workers and shared with the colony. The ants do not chew food for themselves in the usual way; instead, they rely on liquid nutrition by swallowing prey juices and passing solid bits to larvae, which digest and regurgitate it for the colony.

Colony Size and Food Demand

A single army ant colony can contain millions of individuals, which drives the need for enormous amounts of food daily. This is why raids are so intense and cover such large areas, often moving in a nomadic cycle between temporary bivouacs.

Army Ants vs. Leaf-Cutter Ants

Unlike leaf-cutter ants that farm fungus, army ants are hunters and scavengers. They do not eat leaves or grow food; they rely entirely on live prey captured during raids, making them one of the most aggressive foragers in the insect world.

Where Army Ants Live

Most army ants live in Central and South America, though some species are found in Africa and Asia. Their diet and hunting style adapt to the local ecosystem, but the basic strategy of large, mobile raids remains the same across species.
