Argentine Ant Global Mega Colony

In modern times, Argentine ants have formed a vast "mega-colony" that stretches from California to parts of Europe. Ants from distant nests share matching pheromones, so they recognize each other as nestmates instead of enemies. This shared chemical identity lets them cooperate across enormous distances, linking countless nests into one continuous colony. Scientists often describe it as the closest thing to a single global empire in the animal kingdom.
