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
Ant spider Ant spider Ant spiders are members of the family Zodariidae. They are small to medium-sized eight-eyed spiders found world-wide in tropical to warm temperate regions, though there are relatively few species in North America. Some zodariids are ant mimics. Although ant mimicry is quite common in spiders, the form it takes in the zodariids is unusual because, although each species bears a morphological resemblance to the species of ant that forms its prey, the resemblance is not particularly close. It is enhanced by the spider's behaviour. The spiders live in association with a nest of ants of their prey species,
