Ant Megacolony

Argentine ants living in vast numbers across Europe, the US and Japan belong to the same inter-related colony, and will refuse to fight one another. The colony may be the largest of its type ever known for any insect species, and could rival humans in the scale of its world domination. Argentine ants (Linepithema humile) were once native to South America. But people have unintentionally introduced the ants to all continents except Antarctica. In Europe, one vast colony of Argentine ants is thought to stretch for 6,000km along the Mediterranean coast, while another in the US, known as the "Californian large", extends over 900km along the coast of California. A third huge colony exists on the west coast of Japan. The enormous extent of this population is paralleled only by human society
