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. Their colonies are enormous compared to other ant species, and can contain over 20 million individuals. [3]
Colonies of army ants are large compared to the colonies of other Formicidae. Colonies can have over 15 million workers and can transport 3000 prey (items) per hour during the raid period. [14] [20] When army ants forage, the trails that are formed can be over 20 m (66 ft) wide and over 100 m (330 ft) long. [20]
Local arthropod densities remain stable even in the presence of a foraging colony of the ants, in sharp contrast to the decimation a colony of typical army ants imposes on local arthropods.2 Above ground foraging driver and army ants have been observed collecting upwards of 90,000 insects per day in their raids, a number which Even juvenile ...

Two ants fighting over a dead wasp. Wars or conflicts can break out between different groups in some ant species for a variety of reasons. These violent confrontations typically involve entire colonies, sometimes allied with each other, and can end in a stalemate, the complete destruction of one of the belligerents, the migration of one of the groups, or, in some cases, the establishment of ...
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. [1] [2]
An army of driver ants invaded a man's house in Nairobi, Kenya to steal some bread from his larder. The strange occurrence took place on March 16, when the man discovered the ant invasion at ...
Driver ants. Driver ants, from the genus Dorylus, are found in the Old World, especially West Africa and the Congo Basin. Unlike the army ants of the New World, Old World army ants have a functional sting but rarely use it, preferring their razor-sharp, falcate mandibles for defense instead. Dorylus spp. colonies also reach larger sizes than ...
