Scary! Ants form Global Mega-Colony

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. What's more, people are unwittingly helping the mega-colony stick together.

A single mega-colony of ants has colonised much of the world, scientists have discovered.

What’s more, people are unwittingly helping the mega-colony stick together.

Argentine ants (Linepithema humile) were once native to South America. But people have unintentionally introduced the ants to all continents except Antarctica.

These introduced Argentine ants are renowned for forming large colonies, and for becoming a significant pest, attacking native animals and crops.

In Europe, one vast colony of Argentine ants is thought to stretch for 6,000km (3,700 miles) along the Mediterranean coast, while another in the US, known as the “Californian large”, extends over 900km (560 miles) along the coast of California. A third huge colony exists on the west coast of Japan.

While ants are usually highly territorial, those living within each super-colony are tolerant of one another, even if they live tens or hundreds of kilometres apart. Each super-colony, however, was thought to be quite distinct.

But it now appears that billions of Argentine ants around the world all actually belong to one single global mega-colony.

In the late 80s I started investigating UFOs and crop circles and joined the CCCS (Centre for Crop Circle Studies) and a local group researching strange sightings and reports along the south coast of Dorset (UK). In the early ’90s I started my own research group called SPS (Strange Phenomena Studies), this was renamed in 2004 to Cryptoworld.

  1. No one’s saying they don’t have the right, Parodia. This article is, however, breaking the human-centric notion that we are the only species capable of spreading across the globe. Interesting how they’ll fight with their neighbors but not relatives, even from other countries. How many humans can even tolerate family members in their own house?

  2. There’s a lot of anthropomorphism going on in these two comments. Rights? Tolerance? They’re robot-like insects who are practically blind to anything but chemical signals and we’re primates who have evolved highly complex social rules. Concepts like rights and tolerance don’t exist in their world.

  3. Casey, do you actually know that? Have you ever spent any time as an ant? Sure, in all reality, we can believe that is all the ant knows and thinks because of what we’ve learned from science, but we can never be 100% sure. Absence of evidence does not refute anything.
