Rotary Centennial Park. They have not.
And more than a little frightening, when you consider the fact that insects on Earth are estimated to out humans by around million to one. Which is just staggering.
On the contrary, they engaged in friendly antenna-rubbing ant behavior. When they come into contact, they recognize each other by the chemical composition of their cuticles.
Apr 29, This giant colony spans three continents! Ants from the different super-colonies were matched up against each other, to determine their levels of aggression to each other. The fact that these little creatures—that had been were separated by thousands of miles—were so friendly is intriguing.
Apr 30, CC Antweb. Ants are, famously, pretty darn smart little beasties—in groups, at least.
It was found that ants from the smaller super-colonies would be as aggressive to one other as always, but those from the main ones the Californian, larger European and larger Japanese colonies would not. This particular species operates differently to many other ants, living in a variety of ever-shifting temporary nests rather than remaining tied to just one.
Curiously, they also boast up to different queens for every 1, workers!
While ants tend to be incredibly territorial, researchers at the University of Tokyo found an intriguing link between the members of these colonies. These two traits combine to give them great resilience, and along with inadvertent help from humans, surely led to the super-colony spreading across the planet.
