Army Ants | World’s Deadliest | National Geographic -Documentary.

The name army ant (or legionnaire ant or marabunta) is applied to more than 200 species of ants in different pedigrees, because of their aggressive predatory groups known as “raids“, in which a huge number of ants simultaneously feed on a certain territory. Another common feature is that, unlike most ant species, army ants do not build permanent nests: a colony of army ants moves almost continuously throughout its existence. All species are members of the true ant family, Formicidae, but several groups have independently developed the same basic behavioral and ecological syndrome. This syndrome is often called “legionnaire’s behavior“, and it can be an example of convergent evolution. Most of the ants of the New World Army belong to the subfamily Ecitoninae, which contains two tribes: Cheliomyrmecini and Ecitonini. The former contains only the genus Cheliomyrmex, whereas the latter contains four genera: Neivamyrmex, Nomamyrmex, Labidus and Eciton. The largest genus is Neivamy
