Army ant Army ant The name army ant (or legionary ant or marabunta) is applied to over 200 ant species, in different lineages, due to their aggressive predatory foraging groups, known as "raids", in which huge numbers of ants forage simultaneously over a certain area. Another shared feature is that, unlike most ant species, army ants do not construct permanent nests: an army ant colony moves almost incessantly over the time it exists. All species are members of the true ant family, Formicidae, but several groups have independently evolved the same basic behavioral and ecological syndrome. This syndrome is often referred to
Carpenter ant an individual carpenter ant to be recognized as a nestmate, it must, as an adult, go through specific interactions with older members of the nest. This process is also necessary in order for the ant to recognize and distinguish other individuals. If these interactions do not occur in the beginning of adult life, the ant will be unable to be distinguished as a nestmate and unable to distinguish nestmates. Recognition allows for the presence of kin-specific interactions, like kin altruism. Altruistic individuals increase other individuals' fitness at the expense of their own fitness. Carpenter ants perform altruistic actions toward their
