Lestrimelitta Limao
''Lestrimelitta limao'' is a neotropical eusocial bee species found in Brazil and Panama and is part of the Apidae family. It is a species of stingless bees that practices obligate nest robbing. They have never been spotted foraging from flowers, an observation that supports their raiding behavior. Because of their lack of hind corbiculae, they must raid to obtain enough protein in their diet in the form of pollen and nectar. ''Lestrimelitta limao'' secrete a lemon-scented alarm allomone, from which they receive their name, in order to conduct successful raids. ''L. limao'' are hypothesized to produce poisonous honey that is toxic if consumed by humans. Because robber bees are so rare and difficult to observe, there is a limited scope of information available. Taxonomy and phylogeny ''Lestrimelitta limao'' is part of the Apidae family, which consists of bumble bees, euglossines, honey bees, and stingless bees. This species is within the tribe Meliponini. ''L. limao'' usually vis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick Smith (entomologist)
Frederick Smith (30 December 1805 – 16 February 1879) was a British entomologist who worked at the zoology department of the British Museum from 1849, specialising in the Hymenoptera. Smith was born near York to William Smith and went to school at Leeds. He then studied under landscape engraver W.B. Cooke along with his nephew William Edward Shuckard. Together they took an interest in insects, especially the ants and bees. In 1841, following the death of William Bainbridge, he became a curator of the collections and the library of the Entomological Society of London. As an engraver he produced copies based on the works of Turner, Constable and David Roberts. He also worked with Gray arranging Hymenoptera in the British Museum. In 1849 he succeeded Edward Doubleday as a member of the zoologicy department. He then gave up his art work but produced the plates for Wollaston's ''Insecta Maderensia'' (1854) and for papers in the Transactions of the Entomological Society. In 1875, h ...

Hamulus
A hamus or hamulus is a structure functioning as, or in the form of, hooks or hooklets. Etymology The terms are directly from Latin, in which ''hamus'' means "hook". The plural is ''hami''. ''Hamulus'' is the diminutive – hooklet or little hook. The plural is ''hamuli''. Adjectives are ''hamate'' and ''hamulate'', as in "a hamulate wing-coupling", in which the wings of certain insects in flight are joined by hooking hamuli on one wing into folds on a matching wing. ''Hamulate'' can also mean "having hamuli". The terms ''hamose'', ''hamular'', ''hamous'' and ''hamiform'' also have been used to mean "hooked", or "hook-shaped". Terms such as ''hamate'' that do not indicate a diminutive usually refer particularly to a hook at the tip, whereas diminutive terms such as ''hamulose'' tend to imply that something is beset with small hooks. Anatomy In vertebrate anatomy, a hamulus is a small, hook-shaped portion of a bone, or possibly of other hard tissue. In human anatomy, example ...

Hymenoptera Of Brazil
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grayanotoxin
Grayanotoxins are a group of closely related neurotoxins named after '' Leucothoe grayana'', a plant native to Japan originally named for 19th century American botanist Asa Gray. Grayanotoxin I (grayanotaxane-3,5,6,10,14,16-hexol 14-acetate) is also known as andromedotoxin, acetylandromedol, rhodotoxin and asebotoxin. Grayanotoxins are produced by ''Rhododendron'' species and other plants in the family Ericaceae. Honey made from the nectar and so containing pollen of these plants also contains grayanotoxins and is commonly referred to as mad honey. Consumption of the plant or any of its secondary products, including mad honey, can cause a rare poisonous reaction called grayanotoxin poisoning, mad honey disease, honey intoxication, or rhododendron poisoning. It is most frequently produced and consumed in regions of Nepal and Turkey as a recreational drug and traditional medicine. Origin Grayanotoxins are produced by plants in the family Ericaceae, specifically members of the gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetragonisca Angustula
''Tetragonisca angustula'' is a small eusocial stingless bee found in México, Central and South America. It is known by a variety of names in different regions (e.g.'' jataí, yatei, jaty, virginitas, angelitas inglesas, españolita, mariola, chipisas, virgencitas,'' and ''mariolitas''). A subspecies, ''Tetragonisca angustula fiebrigi'', occupies different areas in South America and has a slightly different coloration. ''T. angustula'' is a very small bee and builds unobtrusive nests, allowing it to thrive in urban areas. It also produces large amounts of honey, and is thus frequently kept in wooden hives by beekeepers. ''T. angustula'' hives are often overlooked, and since the bee lacks a stinger, it is not seen as a threat to humans. Many of their behaviors are concerned with colonizing a new nest and producing offspring, demonstrated by their swarming and nursing behaviors, however a special caste of ''T. angustula'' are soldiers who are slightly larger than the workers.

Involucrum
An involucrum (plural involucra) is a layer of new bone growth outside existing bone. There are two main contexts: * In pyogenic osteomyelitis where it is a layer of living bone that has formed about dead bone. It can be identified by radiographically (i.e., with x-rays). * In cetaceans such as whales, it is a thick covering of bone over the middle-ear space. See also *Sequestrum A sequestrum (plural: sequestra) is a piece of dead bone that has become separated during the process of necrosis from normal or sound bone. It is a complication (sequela) of osteomyelitis. The pathological process is as follows: * infection in t ... References Skeletal system {{Musculoskeletal-stub ...

Tergum
A ''tergum'' (Latin for "the back"; plural ''terga'', associated adjective tergal) is the Anatomical terms of location#Dorsal and ventral, dorsal ('upper') portion of an arthropod segment other than the head. The Anatomical terms of location#Anterior and posterior, anterior edge is called the 'base' and posterior edge is called the 'apex' or 'margin'. A given tergum may be divided into hardened plates or sclerites commonly referred to as tergites. In a Thorax (insect anatomy), thoracic segment, for example, the tergum may be divided into an anterior notum and a posterior Scutellum (insect), scutellum. Lateral extensions of a tergite are known as paranota (Greek for "alongside the back") or ''carinae'' (Latin for "keel"), exemplified by the flat-backed millipedes of the order Polydesmida. Kinorhynchs have tergal and sternal plates too, though seemingly not homologous with those of arthropods. Tergo-tergal is a stridulation, stridulatory mechanism in which fine spines of the abdom ...

Apidae
Apidae is the largest family within the superfamily Apoidea, containing at least 5700 species of bees. The family includes some of the most commonly seen bees, including bumblebees and honey bees, but also includes stingless bees (also used for honey production), carpenter bees, orchid bees, cuckoo bees, and a number of other less widely known groups. Taxonomy In addition to its historical classification (honey bees, bumble bees, stingless bees and orchid bees), the family Apidae presently includes all the genera formerly placed in the families Anthophoridae and Ctenoplectridae. Although the most visible members of Apidae are social, the vast majority of apid bees are solitary, including a number of cleptoparasitic species. The old family Apidae contained four tribes (Apinae: Apini, Euglossini and Bombinae: Bombini, Meliponini) which have been reclassified as tribes of the subfamily Apinae, along with all of the former tribes and subfamilies of Anthophoridae and the former f ...

Trigona
''Trigona'' is one of the largest genera of stingless bees, comprising about 32 species, exclusively occurring in the New World, and formerly including many more subgenera than the present assemblage; many of these former subgenera have been elevated to generic status.Michener, C.D. (2000). The Bees of the World. Johns Hopkins University Press Range ''Trigona'' species occur throughout the Neotropical region, including South and Central America, the Mexican lowlands, and the Caribbean islands. They can occur in forests, savannas, and man made environments. ''Trigona'' bees are active all year round, although they are less active in cool environments. Nesting ''Trigona'' nests are constructed from wax they produce and plant resins they collect. They usually nest in tree cavities and underground. Vulture bees Vulture bees comprise three ''Trigona'' species, and are the only bees known to be scavengers. These bees collect and feed on dead animal flesh. Communication Some spe ...
