About 200 army-ant species roam in nomadic groups numbering millions, without building permanent nests.

@nature
From intercontinental supercolonies to urban cracks, war is a persistent part of ant existence.
Kurzgesagt – In a NutshellThe World War of the Ants – The Army Ant
@nature
Army-ant invasions often exterminate prey colonies and consume stolen larvae, preventing those colonies from recovering.

@nature
Leafcutter ants build enormous societies, with nests extending many meters underground and millions of inhabitants assigned specialized labor.

@nature
A successful army-ant invasion can penetrate deep into leafcutter colonies, consume tens of thousands of brood, and leave severe damage.

@nature
Some army-ant hunting columns stretch 100 meters and kill as many as 500,000 animals in a single day.

@nature
On land, ants alone make up about 20% of all animal biomass.

@nature
When army-ant scouts appear, some ants evacuate, carrying their larvae away so the colony can rebuild later.
