Cue “insect overlord” jokes: huge colonies of Argentine ants (Linepithema humile) on four continents may actually be one titanic colony.
It seems that members of each colony will attack other ants from elsewhere on the same continent. But when you put ants from different continents together, they don’t.
Instead ,they seem to recognize each other by the chemical profiles of their antennae and act all friendly, like they’re members of the same…[dun dun dun!]...mega-colony!
In the somewhat purple words of the BBC:
Sorry, population extent doesn’t equal domination. But still, if it’s true, that’s one huge extended family.
By some estimates there are more ants than any other terrestrial organism on Earth.
Good thing they could never unite into one big hive mind and decide to take over the planet and enslave us all to toil in their underground sugar mines.
