Aenictus is a large army ant genus distributed in the Old World tropics and subtropics. [3] It contains about 181 species, [2] making it one of the larger ant genera of the world. [4]
The genus presently has 181 species, [2] distributed through the East Mediterranean, Afrotropical, Oriental, Indo-Australian, and Australian regions. [4] [5] [6] [7] Most of the species are tropical, [6] with terrestrial habitats, foraging in soil, leaf litter, most of the Southeast Asian species forage on the ground, and some on trees [8] and hunting other ant species and termites. [5] [9] [10]
Most species of the genus are specialized predators of other ants, especially of immature stages. [5] [9] [11] Only some Asian species such as Aenictus gracilis , Aenictus laeviceps , Aenictus hodgsoni , and Aenictus paradentatus are known to hunt a variety of invertebrate prey, including ants, using a large number of workers in raids. [5] [8] [12] [13] Foraging raids undertaken by these ants occur both day and night, usually across the ground surface but occasionally also in trees. During raids, numerous workers attack ant nests in a small area, with several workers coordinating their efforts to carry large prey items back to the nest or bivouac. [3] Species of Aenictus are generally small, monomorphic and yellow to dark brown. [10]
