Killer ants
Killer ants is a term to describe any of several species of ants that are predatory, attack en masse when their mounds are disturbed, and can kill animals many times their size, even deer if they are immobilized. They have been called the fiercest predators on Earth. Predator ants kill more individuals than all the big predators combined.
The most commonly cited example of killer ants are the Red Imported Fire Ants (RIFA, IFA, Solenopsis invicta).
Other kinds of killer ants include:
Army and Driver ants appear to be the most dangerous of the killer ants. Driver ants can reduce a tethered cow to polished bone in several weeks. A few cases of human deaths (inebriated or infant) have been reported.
