Ant Mill Phenomenon: How Army Ants Form Deadly Circular Death Spirals
By

Crisp on the outside, thoughtful on the inside. A keeper.
Summary
The article describes the phenomenon of an 'ant mill' or 'death spiral' where army ants become separated from their main foraging party, lose the pheromone track, and begin following one another in a continuously rotating circle. This self-organizing behavior can lead to ants dying from exhaustion. The phenomenon has been reproduced in laboratories and ant colony simulations, and is a side effect of the ants' collective behavior structure.
Key quotes
· 4 pulledAn ant mill is an observed phenomenon in which a group of army ants, separated from the main foraging party, lose the pheromone track and begin to follow one another, forming a continuously rotating circle.
This circle is commonly known as a 'death spiral' because the ants might eventually die of exhaustion.
It has been reproduced in laboratories and in ant colony simulations.
The phenomenon is a side effect of the self-organizing structure of ant colonies.
