The reasons that can lead ant colonies to clash are varied and depend on the species, locations, and contexts. For a number of them, such as leafcutter ants Atta laevigata, wood ants of the genus Formica, certain species of the genus Carebara, or giant ants Dinomyrmex gigas, it is a matter of territory covered and thus the available food for the different colonies.
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 ...
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]
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 ...
Argentine ant colonies almost invariably have many reproductive queens, as many as eight for every 1,000 workers. The seasonal low occurs in mid-winter, when 90% of a representative colony consists of workers and the remainder of queens, and no reproductive activity and minimal birthing.
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.
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 ...
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 ...
