The name army ant (or legionary ant or marabunta [1]) is applied to over 200 ant species in different lineages. Because of their aggressive predatory foraging groups, known as "raids", a huge number of ants forage simultaneously over a limited area.
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 army ants have a bi-phasic lifestyle in which they alternate between a nomadic phase and a statary phase. In the statary phase, which lasts about three weeks, the ants remain in the same location every night. They arrange their own living bodies into a nest, protecting the queen and her eggs in the middle.
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 ...
In some parts of the world (mainly Africa and South America), large ants, especially army ants, are used as surgical sutures. The wound is pressed together and ants are applied along it. The ant seizes the edges of the wound in its mandibles and locks in place. The body is then cut off and the head and mandibles remain in place to close the wound.
