Ecitoninae
Ecitoninae is an ant subfamily. They are carnivorous ants that are characterized by organizing periodic expeditions of thousands of individuals. They do not build colonies and have a constantly moving way of life. Some birds regularly follow these expeditions in order to find insects and other small animals that try to escape the attack of ants. Distribution They are found in America, from the southern United States to northern Argentina. Ecology This group of ants (with Aenictinae and Dorylinae subfamilies) they represent the nomadic ants that do not build anthills, and constantly go from one camp to another, at the same time carrying with them all the food for the larvae, which consists of prey of the invertebrates they attack.

Ants
Ants are Eusociality, eusocial insects of the Family (biology), family Formicidae and, along with the related wasps and bees, belong to the Taxonomy (biology), order Hymenoptera. Ants evolved from Vespoidea, vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified. They are easily identified by their geniculate (elbowed) Antenna (biology), antennae and the distinctive node-like structure that forms their slender waists. Ants form Ant colony, colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals. Larger colonies consist of various castes of sterile, wingless females, most of which are workers (ergates), as well as soldiers (dinergates) and other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Larvae
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are ...

Neivamyrmex
''Neivamyrmex'' is a genus of army ants in the subfamily Dorylinae. Range ''Neivamyrmex'' species can be found from the central United States to southern Argentina. Taxonomy As of 2021, 129 ''Neivamyrmex'' species have been identified. However, most research pertaining to this genus is based on a single species, ''Neivamyrmex nigriscens'', from which knowledge about ''Neivamyrmex'' overall is derived. Many species are known based only on a small number of male individuals. Biology ''Neivamyrmex'' do not build permanent nests; instead, colonies are nomadic, establishing temporary bivouacs every night before moving on to a new location. Most species are predominantly subterranean, but they will occasionally forage above ground at night or on cloudy days. The larvae and pupae of other ant species are the principle food of ''Neivamyrmex'', including ants of the genera '' Veromessor'', ''Pheidole'', ''Solenopsis'', and ''Formica ''Formica'' is a genus of ants of the fa ...

Eciton
''Eciton'' is a New World army ant genus that contains the most familiar species of army ants. The most predominant and well-known species is '' Eciton burchellii'', which is also more commonly known as the army ant and is considered the type species. '' Eciton burchellii'' and '' Eciton hamatum'' are the most visible and best studied of the New World army ants because they forage above ground and during the day, in enormous raiding swarms. Their range stretches from southern Mexico to the northern part of Argentina. Life cycle ''Eciton'' army ants have a bi-phasic lifestyle in which they alternate between a nomadic phase and a statary phase. In the statary phase, which lasts about three weeks, the ants remain in the same location every night. They arrange their own living bodies into a nest, protecting the queen and her eggs in the middle. Such a temporary home is called a " bivouac". In the nomadic phase the ants move their entire colony to a new location nearly every night ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms ...

Arthropoda
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior organs; it has an open circulatory system. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. Their nervous system is "lad ...
