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 ...
In ants, social conflicts, sex conflicts, or caste conflicts can exist. These conflicts occur within the same colony or supercolony at various levels: on an individual scale, between two or more specific ants; on the scale of sex, between males and females; or on the scale of different castes, between queens and workers.
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]
In 1997, UC San Diego researchers observed fighting between different Argentine ants kept in lab, and in 2004 scientists began to map out the boundaries of the different supercolonies that clashed in San Diego. On the border of the Very Large Colony and the Lake Hodges Colony thirty million ants die each year, on a battlefront that covers many ...
An ant colony is a population of ants, typically from a single species, capable of maintaining their complete lifecycle. Ant colonies are eusocial, communal, and efficiently organized and are very much like those found in other social Hymenoptera, though the various groups of these developed sociality independently through convergent evolution.

Head view of a soldier with characteristically shaped mandibles. Unlike most ant species, Eciton burchellii is polymorphic, meaning that features amongst smaller groups within the colony vary in size: a colony contains workers ranging from 3 mm to 12 mm, with each specific "caste" suited to specialized tasks.
D. laevigatus colonies are fairly small for army ant colonies, ranging from 30,000 to 1,000,000 individuals. Because the colonies prefer long-term food exploitation and stable column foraging systems to massive raids, there is little pressure for the colonies to expand and support the massive numbers of individuals common in surface-hunting ...
An ant supercolony is an exceptionally large ant colony, consisting of a high number of spatially separated but socially connected nests of a single ant species (meaning that the colony is polydomous), spread over a large area without territorial borders.
