Why do ants often move in a row?

Whenever out looking for food or going home, ants have a habit of moving in a row. Why do they do that? Let's find out through the article below.

Ants are creatures that organize herds. Due to the large number of ants, the move or coordination needs to be organized. Moving in long lines is also a manifestation of fellow cognitive behavior and leads the way through taste.

Specifically, when an ant finds food, it will bring a small part to the nest. On the way, that ant will secrete a chemical called pheromone. The pheromone smell of each colony, the ant species are different to distinguish them from other colonies.

Following this pheromone trail, the other ants in the herd can find food. Because the pheromone is volatile, the ant that travels ahead will secrete this chemical so that the ants behind it can determine the location of food and the way back to the nest. This makes ants tending to line up.

The movement in rows also helps ants easily touch their heads, body contact to identify members of the herd through checking pheromone smells of the same species. If any ants of another herd are found, they will immediately scare off strangers.
