An 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 ...
In 1921, the U.S. naturalist Charles William Beebe reported on the ant mill phenomenon, which trace pheromones can trigger in army ants: If the animals are separated from the main trail of the colony, the blind ants follow the pheromone trails of ants running in front of them. These run in large circles until complete exhaustion or death ...
For example, ants mark their paths with pheromones consisting of volatile hydrocarbons. Certain ants lay down an initial trail of pheromones as they return to the nest with food. This trail attracts other ants and serves as a guide. [21] As long as the food source remains available, visiting ants will continuously renew the pheromone trail.
A phenomenon where army ants follow each other in circles, sometimes until they die — and thus known as an “ant death spiral” — was captured on camera at a university in Venezuela ...
Ant communication in most species involves pheromones, which is a method using chemical trails for other ants or insects to find and follow. [ 1 ] However, ants of some species can communicate without using pheromones or chemical trails in general.
Ants do this when they lose track of their colony, and sometimes will keep walking until death Ants walk around in a never-ending circle known as an “ant death spiral” [Video] Skip to main content
Trail pheromones are semiochemicals secreted from the body of an individual to affect the behavior of another individual receiving it. Trail pheromones often serve as a multi purpose chemical secretion that leads members of its own species towards a food source, while representing a territorial mark in the form of an allomone to organisms outside of their species.

They use special pheromones to mark scented trails for other ants to follow. With medium-sized bodies, media ants are super strong and can carry 20 times their own body weight!
