Ants fight wars. I don’t know if any of you know this, but this came as a supprise to me.
“ants employ propaganda, deception, and skilled surveillance and mass assaults singly or in combination to overcome their enemies. In extreme cases some fight by dropping stones on their enemies, while others conduct slave raids to increase the size of the labor and fighting force”
“Battles among ants may involve a huge number of individuals. Many species use trail pheromones to attract workers to the site of skirmishes. Among European wood ants, battles may last for weeks and result in thousands of dead ants each day”
Ants even plunder, or steal!
“ Some ants will raid the colonies of other ants, taking the pupae with them, which once hatched act as workers in the raider's colonies despite not being genetically related to the queen. A few species, such as the warrior ants (Neivamyrex pilosus), have become utterly dependent on such slaves, to the point of being otherwise unable to feed themselves.”
