Little Fire Ants

Wasmannia auropunctata – little fire ants
Buenos Aires, Argentina

One of the world’s worst invaders, the little fire ants have spread from the new world tropics to warmer regions around the globe, becoming especially problematic on oceanic islands. The ants above, though, are from an innocuous native population in northern Argentina. They arrived at a cookie bait at the Costanera Sur reserve, barely noticeable specks of orange just over a millimeter long.

Wasmannia has a painful sting for such a small insect, and the ants do this annoying thing where they’ll wander around on your body for an hour or two before deciding to stick it to you. So there you’ll be, relaxing at the bar long after getting in from the field, and ZAM!  Right between the shoulder blades.
