myrmepropagandistHere is a classic video of army ants and leaf cutter ants menacing each other, but mostly maintaining a border so each can get on with their work.
It's remarkable and important that you don't see them fully attacking each other, a battle between these colonies could destroy them both.

myrmepropagandistI like how the leafcutter majors stand to tiptoe and loom down at the army ants.
Army ants are blind so, the direction the feel the leafcutter coming from might inform how the weight the threat.
The army ants often raid the nests of other ants for larvae and the leafcutters have behaviors to deter this.

Shocking really.
