Dorylus Gaudens
''Dorylus'', also known as driver ants, safari ants, or siafu, is a large genus of army ants found primarily in central and east Africa, although the range also extends to southern Africa and tropical Asia. The term siafu is a loanword from Swahili language, Swahili, and is one of numerous similar words from regional Bantu languages used by indigenous peoples to describe various species of these ants. Unlike the New World members of the former subfamily Ecitoninae (now Dorylinae), members of this genus form temporary subterranean Bivouac (ants), bivouacs in underground cavities which they excavate and inhabit - either for a few days or up to three months. Also unlike some New World army ants, driver ants are not specialized predators of other species of ant, instead being more generalistic with a diet consisting of a diversity of arthropods. Ant colony, Colonies are enormous compared to other army ants and can contain over 20 million individuals. As with their American counterparts ...

Dorylus Gribodoi
''Dorylus gribodoi'' is a West African species of army ants in the genus ''Dorylus''. Habitat and distribution The species occurs in West Africa, from Guinea and Liberia to Cameroon. It is restricted to humid habitats such as rainforest and gallery forest in mixed savanna–forest landscapes and occurs at least up to 1600 m above sea level. Biology Raids are conducted in the leaf-litter stratum. Workers retreat in tunnels when disturbed or exposed to sun. Limited observations indicate that the species seems to prey almost exclusively on earthworms, but this information has to be viewed with caution since variation in prey composition can be considerable in other ''Dorylus'' species. Chimpanzees are known to feed on ''D. gribodoi'' at two sites (Bossou in Guinea and Taï in Ivory Coast); they either use sticks to "dip" for ant workers at trails or nests or open nests and take brood and workers with their hands. Nests are much less conspicuous than those of driver ant species an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
