Most ant species will send individual scouts to find food sources and later recruit others from the colony to help; however, army ants dispatch a cooperative, leaderless group of foragers to detect and overwhelm the prey at once. [3] [5] Army ants do not have a permanent nest but instead form many bivouacs as they travel.
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 ...
Army ant bivouac. A bivouac is an organic structure formed by migratory driver ant and army ant colonies, such as the species Eciton burchellii.A nest is constructed out of the living ant workers' own bodies to protect the queen and larvae, and is later deconstructed as the ants move on.
Eciton is a New World army ant genus that contains the most familiar species of army ants. The most predominant and well-known species is Eciton burchellii, which is also more commonly known as the army ant and is considered the type species.
To see Bala again, Z exchanges places with his best friend, a soldier ant named Weaver, and joins the army, where he befriends staff sergeant Barbatus. The ants are unaware that General Mandible, the army's leader and Bala's fiancé, is secretly sending the soldiers loyal to the colony's queen to die so he can stage a coup d'état.
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 ...
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 ...
However, a mature colony of several million workers faces very few dangers. No known predator, except the mostly subterranean army ant Nomamyrmex esenbeckii, actively attacks the nests, and even other highly aggressive army ants show a healthy respect for an A. sexdens colony. If spared from floods and human activity, the colony is usually ...
