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 ant colonies using the gamergate system, where all workers have a spermatheca and thus the potential to become egg-laying individuals, conflicts are much more violent and are a regular part of colony management. [4] [8] Workers may engage in contests and confrontations to determine who will have the right or possibility to lay eggs. In these ...
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 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.

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]
Colonies of real army ants have only one queen, so when she dies, the workers may try to join another colony, or the rest of the colony also dies; Carebara colonies can have many (up to 16) queens. Carebara species perform a nuptial flight; real army-ant queens have no wings (queens and workers of the Dorylus species are even blind) and mate on ...
Colonies of P. lucidus and its close relatives only raid nests of the slave species already present in the dulotic nest, an early clue that these host specialists might, in fact, be separate species. On the odd occasion when the nest of a different ant species was raided, the pupae brought back to the dulotic nest were likely to be consumed.
Polyergus rufescens is a species of slave-making ant native to southern Europe and parts of Asia, commonly referred to as the European Amazon ant or as the slave-making ant. It is an obligatory social parasite , unable to feed itself or look after the colony and reliant on ants of another species to undertake these tasks.
