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 ...

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 ...
The reasons that can lead ant colonies to clash are varied and depend on the species, locations, and contexts. For a number of them, such as leafcutter ants Atta laevigata, wood ants of the genus Formica, certain species of the genus Carebara, or giant ants Dinomyrmex gigas, it is a matter of territory covered and thus the available food for the different colonies.

Colonies of real army ants have only one queen, so when she dies, the workers may try to join another colony, or the rest of the colony also dies; Carebara colonies can have many (up to 16) queens. Carebara species perform a nuptial flight; real army-ant queens have no wings (queens and workers of the Dorylus species are even blind) and mate on ...

Eciton burchellii is a species of New World army ant in the genus Eciton. This species performs expansive, organized swarm raids that give it the informal name, Eciton army ant. [2] This species displays a high degree of worker polymorphism. Sterile workers are of four discrete size-castes: minors, medias, porters (sub-majors), and soldiers ...
