Tandem Running
Tandem running is a pair movement coordination observed in ants and termites. In ants, tandem running is used for social learning, by which one ant leads another native ant from the nest to the food source it has found. Tandem running is also used to find and choose better, new nest sites to which the colony can emigrate. The follower ant maintains contact with the lead ant by frequently touching the leader's legs and abdomen with its antennae. As predators, scavengers, and herbivores, ants have a variety of food sources, for which they may journey as far as 200 meters from their nest, spraying a scent trail as they go. To lead their kin to new food sources, ants demonstrate one of the few examples of interactive teaching outside of the mammalian class. Social learning by teaching requires that the naive observer change its behavior and acquire some skills or knowledge faster than it would have independently and that the teacher incur some cost. In order for the follower ant to le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Termite
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood eating cockroaches of the genus ''Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees a ...

Ant Colony
An ant colony is a population of a single ant species capable to maintain its 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. The typical colony consists of one or more egg-laying queens, numerous sterile females (workers, soldiers) and, seasonally, many winged sexual males and females. In order to establish new colonies, ants undertake flights that occur at species-characteristic times of the day. Swarms of the winged sexuals (known as alates) depart the nest in search of other nests. The males die shortly thereafter, along with most of the females. A small percentage of the females survive to initiate new nests. Names The term "ant colony" refers to a population of workers, reproductive individuals, and brood that live together, cooperate, and treat one another non-aggressively. ...

''Nature'' is a British weekly scientific journal founded and based in London, England. As a multidisciplinary publication, ''Nature'' features peer-reviewed research from a variety of academic disciplines, mainly in science and technology. It has core editorial offices across the United States, continental Europe, and Asia under the international scientific publishing company Springer Nature. ''Nature'' was one of the world's most cited scientific journals by the Science Edition of the 2019 ''Journal Citation Reports'' (with an ascribed impact factor of 42.778), making it one of the world's most-read and most prestigious academic journals. , it claimed an online readership of about three million unique readers per month. Founded in autumn 1869, ''Nature'' was first circulated by Norman Lockyer and Alexander Macmillan as a public forum for scientific innovations. The mid-20th century facilitated an editorial expansion for the journal; ''Nature'' redoubled its efforts in exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temnothorax Albipennis
''Temnothorax albipennis'', the rock ant is a species of small ant in the subfamily Myrmicinae. It occurs in Europe and builds simple nests in rock crevices. Description This species has the typical ant body pattern of head, mesosoma and metasoma, with the first two segments of the metasoma forming a distinct waist. It is light brown and has a few short pale coloured hairs. The antennae are elbowed and there are a pair of compound eyes and three ocelli. Biology 180px, left, View of head from above As with other ants, there is a single, relatively large queen that lays eggs in the nest and a large number of workers. These are all non-breeding females and leave the nest to forage and collect building materials for its construction and repair. ''T. albipennis'' builds simple nests in cracks in rocks, enclosed by walls built from tiny pebbles and grains of sand. In an experiment where two sizes of sand grain were offered to ants that were foraging for building materials, the ants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diacamma Rugosum
''Diacamma rugosum'', also known as the Bornean queenless ant, is a species of ant of the subfamily Ponerinae. It is found in many countries throughout Southeast Asia. 20 subspecies are recognized. ''D. rugosum'' is noted for being one of the only species of ants to completely lack a queen caste. Reproduction is done entirely by workers, with all workers being fertile upon birth. However, reproduction is kept strictly under control in the nest, with only one dominant female, or gamergate, laying all of the eggs. The gamergate will render workers sterile by mutilating their vestigial wing buds as soon as they pupate. These infertile workers, called callows, will remain loyal to the present gamergate and allow her to exercise control over the rest of the workers. This works to reduce colony infighting as it makes usurpation virtually impossible, and the only time the gamergate is replaced is if she dies naturally.

Camponotus Consobrinus
The banded sugar ant (''Camponotus consobrinus''), also known as the sugar ant, is a species of ant native to Australia. A member of the genus '' Camponotus'' in the subfamily Formicinae, it was described by German entomologist Wilhelm Ferdinand Erichson in 1842. Its common name refers to the ant's liking for sugar and sweet food, as well as the distinctive orange-brown band that wraps around its gaster. The ant is polymorphic and relatively large, with two different castes of workers: major workers (also known as soldiers), and minor workers. These two group of workers measure around in length, while the queen ants are even larger. Mainly nocturnal, banded sugar ants prefer a mesic habitat, and are commonly found in forests and woodlands. They also occur in urban areas, where they are considered a household pest. The ant's diet includes sweet secretions that are retrieved from aphids and other insects that it tends. This species is a competitor of the meat ant (''Iridomyr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pheromone Trail
Trail pheromones are semiochemicals secreted from the body of an individual to affect the behavior of another individual receiving it. Trail pheromones often serve as a multi purpose chemical secretion that leads members of its own species towards a food source, while representing a territorial mark in the form of an allomone to organisms outside of their species. Specifically, trail pheromones are often incorporated with secretions of more than one exocrine gland to produce a higher degree of specificity. Considered one of the primary chemical signaling methods in which many social insects depend on, trail pheromone deposition can be considered one of the main facets to explain the success of social insect communication today. Many species of ants, including those in the genus ''Crematogaster'' use trail pheromones. Background In 1962, Harvard professor Edward O. Wilson published one of the first concrete studies constructing the groundwork for the notion of trail pheromones. Clai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaster (insect Anatomy)
The gaster is the bulbous posterior portion of the metasoma found in hymenopterans of the suborder Apocrita ( bees, wasps and ants). This begins with abdominal segment III on most ants, but some make a constricted postpetiole out of segment III, in which case the gaster begins with abdominal segment IV. Certain ants in the genus '' Cataglyphis'', specifically ''Cataglyphis bicolor'' and ''Cataglyphis fortis'', have a cubiform petiole that allows them to decrease their inertia Inertia is the idea that an object will continue its current motion until some force causes its speed or direction to change. The term is properly understood as shorthand for "the principle of inertia" as described by Newton in his first law ... (and therefore increase their speed) by raising their gaster into an upright position. References Insect anatomy {{insect-anatomy-stub de:Gaster ...

Mastotermes Darwiniensis
''Mastotermes darwiniensis'', common names giant northern termite and Darwin termite, is a termite species found only in northern Australia. It is the most primitive extant termite species. Evolutionary significance This species shows uncanny similarities to certain cockroaches, the termites' closest relatives. These similarities include the anal lobe of the wing and the laying of eggs in bunches, rather than singly. It is the only living member of its genus '' Mastotermes'' and its family Mastotermitidae, though numerous fossil taxa are known. The termites were traditionally placed in the Exopterygota, but such an indiscriminate treatment makes that group a paraphyletic grade of basal neopterans. Thus, the cockroaches, termites, and their relatives are nowadays placed in a clade called the Dictyoptera. These singular termites appear at first glance like a cockroach's abdomen stuck to a termite's fore part. Their wings have the same form as those of the roaches, and its eggs are ...
