Scientific name: Eciton burchellii
Found in Peru all the way to Mexico, it’s one of the world’s most widely known, and most scary, army ants. There is a huge difference between worker ants and soldier ants within this genus. The soldier ants have huge, long teeth. Their tall, strong bodies are over ten times the size of the average worker ants, which could reach 8-10 mm. They do not have a fixed nest, and the whole colony is always on the march. The huge colony of millions of ants can hunt almost any creature. So, you’d better run away as soon as possible when you see them.
