Remember the smell of the enemy

The ant nests, one of the oldest and most effective social structures, can together form an integrated memory of their opponents.

Experts at the University of Melbourne (Australia) have followed the behavior of a tropical ant with the scientific name Oecophylla smaragdina , which is nesting in trees. Each team can accommodate 500,000 worker ants.

Ants can detect enemies immediately thanks to collective knowledge collected by the whole team

They discovered that when an ant fought against an intruder from another ants, it would remember the enemy's smell well and pass it on to all the rest of the team, like a 'collective knowledge'.

This helps their teammates immediately point out another ant from the opponent, according to a report published in the journal Naturwissenschaften.

For many ants, chemicals are the key point for them to function as a society. Insects identify members of the same nest with specific chemicals that cover their bodies.

This allows insects to smell anyone who intends to enter their nest, according to a University of Melbourne study.
