Introduction

This Kurzgesagt video explores the widespread warfare among ants, focusing on the aggressive behavior of army ants (fourmis légionnaires). It highlights the scale of ant conflicts, their societal structures, and the diverse strategies employed by different ant species to survive these encounters, including the leaf-cutter ants' formidable defenses.

Key Takeaways

• Ants, comprising 20% of terrestrial animal biomass, engage in constant warfare across numerous species and colonies.
• Army ants, nomadic and numbering in the millions, form massive raiding columns that decimate insect and small vertebrate populations.
• Army ants frequently target other social insects like termites, wasps, and rival ant colonies. Their overwhelming numbers often lead to colony destruction.
• While some ant species flee or create defensive bunkers upon encountering army ants, leaf-cutter ants engage in direct, large-scale battles, utilizing specialized soldier ants and defensive formations. Even with significant defensive capabilities, leaf-cutter ant colonies are vulnerable to some particularly aggressive army ant species like Nomamyrmex esenbeckii.
• Ant warfare, occurring at various scales from small skirmishes to vast intercontinental conflicts involving supercolonies, is an inherent aspect of ant existence.
