Atta (genus)
''Atta'' is a genus of ants of the Neotropical realm belonging to the ant subfamily Myrmicinae. In English often the species are known as leafcutter ants, though that name is shared with members of the genus '' Acromyrmex''. Workers of ''Atta'' ants gather plant material from the colony's local area, carry the plant parts into the colony's underground chambers, and there fungus grows on it. All the nest's ants feed on that fungus, not the plant material they collect. Leafcutters don't sting, thus inject no venom, although they are known as strong biters. Life Cycle It's unclear how many species the genus ''Atta'' comprises. GBIF lists over 60 -- though many of those name are regarded as "doubtful" -- while the Catalogue of Life lists only 16. As with all ants, ''Atta'' species undergo complete metamorphosis in which each individual ant hatches from an egg as a larva, the larva grows until it forms a pupa, from which later emerges an adult ant. Among adults leafcutter ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atta Colombica
''Atta colombica'' is one of 47 species of leafcutter ants. This species is part of the Attini tribe (the fungus-growing ants). Description Workers of this species are maroon in colour, and are entirely matte, with no shiny spots. Distribution This species ranges from Guatemala to Colombia, and can also be found in Costa Rica and Panama. Nests ''A. colombica'' produces visible refuse dumps of spent fungus on the surface. These dumps often take the form of large, conical mounds, and are located to the side of the main soil mounds. Lines of workers carry the spent fungus from the nest to the dumps. They deposit the grayish-white pellets at the peak of the mounds, which produces the conical shape. This behaviour is different from ''Atta cephalotes, A. cephalotes'', which deposit their refuse in subterranean dumps. The number of workers in a colony is estimated to be 1.0-2.5 million. Behavior A colony of ''A. colombica'' harvests, on average, of plant biomass per year (dry we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larva
A larva (; : larvae ) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage. Animals with indirect development such as insects, some arachnids, amphibians, or cnidarians typically have a larval phase of their life cycle. A 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. In the case of smaller primitive arachnids, the larval stage differs by having three instead of four pairs of legs. 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 lar ...

Nuptial Flight
Nuptial flight is an important phase in the reproduction of most ant, termite, and some bee species. It is also observed in some fly species, such as '' Rhamphomyia longicauda''. During the flight, virgin queens mate with males and then land to start a new colony, or, in the case of honey bees, continue the succession of an existing hived colony. The winged version of ants and termites are known as alates. Before the flight A mature ant colony seasonally produces winged virgin queens and males, called alates. Unfertilized eggs develop into males. Fertilized eggs usually develop into wingless, sterile workers, but may develop into virgin queens if the larvae receive special attention. Within a few days after they have emerged (eclosed) from the pupa case, males are "quickly converted into single-purpose sexual missiles." Young queens and males stay in their parent colony until conditions are right for the nuptial flight. The flight requires clear weather since rain is d ...

Army Ants
The name army ant (or legionary ant or ''marabunta'') is applied to over 200 ant species in different lineages. Because of their aggressive predatory foraging groups, known as "raids", a huge number of ants forage simultaneously over a limited 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 behavioural and ecological syndrome. This syndrome is often referred to as "legionary behaviour", and may be an example of convergent evolution. Most New World army ants belong to the genera '' Cheliomyrmex'', ''Neivamyrmex'', '' Nomamyrmex'', '' Labidus'', and '' Eciton''. The largest genus is ''Neivamyrmex'', which contains more than 120 species; the most predominant species is '' Eciton burchellii''; its common name "army ant" is considered t ...

Mandibles
In jawed vertebrates, the mandible (from the Latin ''mandibula'', 'for chewing'), lower jaw, or jawbone is a bone that makes up the lowerand typically more mobilecomponent of the mouth (the upper jaw being known as the maxilla). The jawbone is the skull's only movable, posable bone, sharing joints with the cranium's temporal bones. The mandible hosts the lower teeth (their depth delineated by the alveolar process). Many muscles attach to the bone, which also hosts nerves (some connecting to the teeth) and blood vessels. Amongst other functions, the jawbone is essential for chewing food. Owing to the Neolithic advent of agriculture (), human jaws evolved to be smaller. Although it is the strongest bone of the facial skeleton, the mandible tends to deform in old age; it is also subject to fracturing. Surgery allows for the removal of jawbone fragments (or its entirety) as well as regenerative methods. Additionally, the bone is of great forensic significance. Structure In h ...

Superorganism
A superorganism, or supraorganism, is a group of synergetically interacting organisms of the same species. A community of synergetically interacting organisms of different species is called a '' holobiont''. Concept The term superorganism is used most often to describe a social unit of eusocial animals in which division of labour is highly specialised and individuals cannot survive by themselves for extended periods. Ants are the best-known example of such a superorganism. A superorganism can be defined as "a collection of agents which can act in concert to produce phenomena governed by the collective", phenomena being any activity "the hive wants" such as ants collecting food and avoiding predators, or bees choosing a new nest site. In challenging environments, micro organisms collaborate and evolve together to process unlikely sources of nutrients such as methane. This process called syntrophy ("eating together") might be linked to the evolution of eukaryote cells and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Division Of Labor
The division of labour is the separation of the tasks in any economic system or organisation so that participants may specialise (Departmentalization, specialisation). Individuals, organisations, and nations are endowed with or acquire specialised capabilities, and either form combinations or trade to take advantage of the capabilities of others in addition to their own. Specialised capabilities may include equipment or natural resources as well as skills. Training and combinations of equipment and other assets acting together are often important. For example, an individual may specialise by acquiring tools and the skills to use them effectively just as an organisation may specialise by acquiring specialised equipment and hiring or training skilled operators. The division of labour is the motive for trade and the source of economic interdependence. An increasing division of labour is associated with the growth of total Output (economics), output and trade, the rise of capitalis ...

Parasitism
Parasitism is a close relationship between species, where one organism, the parasite, lives (at least some of the time) on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson characterised parasites' way of feeding as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoridae
The Phoridae are a family of small, hump-backed flies resembling fruit flies. Phorid flies can often be identified by their escape habit of running rapidly across a surface rather than taking flight. This behaviour is a source of one of their alternate names, scuttle fly. Another vernacular name, coffin fly, refers to '' Conicera tibialis''. About 4,000 species are known in 230 genera. The most well-known species is cosmopolitan '' Megaselia scalaris''. At 0.4 mm in length, the world's smallest fly is the phorid '' Euryplatea nanaknihali''. Description Phorid flies are minute or small – 0.5–6 mm (– in) in length. When viewed from the side, a pronounced hump to the thorax is seen. Their colours range from usually black or brown to more rarely yellow, orange, pale grey, and pale white. The head is usually rounded and in some species narrowed towards the vertex. The vertex is flat. In some species, the ocellar callus is swollen and highly raised above the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf (: leaves) is a principal appendage of the plant stem, stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the Shoot (botany), shoot system. In most leaves, the primary Photosynthesis, photosynthetic Tissue (biology), tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, Trichome, hairiness, the number of stomata (pores that intake and output gases), the amount and ...
