In many regards, ant societies often appear to be a replica of human societies on a reduced scale: "social organisation", hierarchy, specialisation of tasks, inventiveness, adaptation, communication…
Most often hardworking and diligent, ants can also be formidable warriors.
Some carnivorous species – such as fire ants – devastate everything in their paths and pose real ecological problems in certain regions of the world. To such a point that researchers and scientists are now preparing a whole arsenal to combat these uncontrollable cuirassed cohorts: lethal lures based on pheromones, aerial attacks by phorid flies, etc.

However, the art of war is not a characteristic of all ant species. Certain more pacific civilisations have developed their gifts in other domains: architecture, farming and breeding, weaving, etc.
We humans have penetrated little by little the mysteries of ants and use these tiny insects to our own benefit. "Honey ants" are literally venerated by Australian aborigines for their talents in confectionary

Homeopathy and the Chinese pharmacopoeia use ants widely in powder form or in infusions, and the antibacterial substances secreted by certain species have been closely studied by modern biology.
Researchers have even gone as far as to create models of ant behaviour for application in telecommunications and telephony. Using the pheromones that they emit, ants always find the shortest path between two points. Inspired by this logic, the idea is to apply this model to the routing of messages within a telecommunications network.


Whereas the chemical language of ants is now proven, the study of their means of communication by sound has only just begun. It appears that ants are allergic to aeroplanes and cannot bear low frequencies.
