Eurybrachyidae
Eurybrachidae (sometimes misspelled "Eurybrachyidae" or "Eurybrachiidae") is a small family of planthoppers with species occurring in parts of Asia, Australia and Africa. They are remarkable for the sophistication of their automimicry. Etymology The family name is derived from the Greek () and (), meaning "broad" and "short". This presumably reflects the shape of adults of representative species. Description Eurybrachidae generally resemble related families of planthoppers in the Fulgoromorpha. They are moderate-sized insects, generally 1 to 3 cm long when mature, but they are unobtrusive and camouflaged with brown, grey or green blotches, mimicking foliage, bark or lichens. Their mottled camouflage patterns are most intense on the large forewings of many species, hiding the broad and often aposematically colourful abdomen. The frons of the head is characteristic, being broader than it is long. File:Paropioxys jucundus dorsal.jpg , '' Paropioxys jucundus''dorsal v ...

Planthopper
A planthopper is any insect in the infraorder Fulgoromorpha, in the suborder Auchenorrhyncha, a group exceeding 12,500 described species worldwide. The name comes from their remarkable resemblance to leaves and other plants of their environment and that they often "hop" for quick transportation in a similar way to that of grasshoppers. However, planthoppers generally walk very slowly. Distributed worldwide, all members of this group are plant-feeders, though surprisingly few are considered pests. The infraorder contains only a single superfamily, Fulgoroidea. Fulgoroids are most reliably distinguished from the other Auchenorrhyncha by two features; the bifurcate ("Y"-shaped) anal vein in the forewing, and the thickened, three-segmented antennae, with a generally round or egg-shaped second segment (pedicel) that bears a fine filamentous arista. Overview Planthoppers are laterally flattened and hold their broad wings vertically, in a tent-like fashion, concealing the sides of t ...

Amalaberga (planthopper)
Amalaberga was the daughter of Amalafrida, daughter of Theodemir, king of the Ostrogoths. Her father is unknown, her uncle was Theodoric the Great. Around 510, she was married to Hermanfrid, son of the Thuringian ruler Bisinus and his Lombard wife Menia. Hermanfrid and his brothers Baderic and Bertachar succeeded their father as co-rulers, while their mother returned to her people, where their sister, Raicunda, married Wacho, king of the Lombards. Hermanfrid and Amalaberga had two children: a son named Amalafrid and a daughter Rodelinda. Amalaberga is said to have encouraged Hermanfrid to make war on his brothers and become sole ruler. Bertachar was killed in battle, possibly as early as 525. Hermanfrid then sought the help of Theuderic I, the Merovingian king of Austrasia, to attack Baderic and seize control of all of Thuringia. After Baderic was defeated and beheaded by the Franks, Hermanfrid reneged on certain promised land concessions. Theuderic then persuaded his bro ...

Eurybrachys
''Eurybrachys'' is a genus of bugs in the family Eurybrachidae (tribe Eurybrachini). First formally named in 1834 by French entomologist Félix Édouard Guérin-Méneville, ''Eurybrachys'' is the type genus of the family Eurybrachidae. The spelling ''Eurybrachis'', by the author, is considered an unaccepted orthographic variant (spelling mistake). Species in this genus occur in Asia. Species , ''Fulgoromorpha Lists On the Web'' (FLOW) includes the following 16 species in the genus ''Eurybrachys'': #'' Eurybrachys apicalis'' #'' Eurybrachys apicata'' #'' Eurybrachys dilatata'' #'' Eurybrachys dotata'' #'' Eurybrachys ferruginea'' #'' Eurybrachys fletcheri'' #'' Eurybrachys lepeletierii'' #'' Eurybrachys manifesta'' #'' Eurybrachys mysorensis'' #'' Eurybrachys rubrescens'' #'' Eurybrachys rubricincta'' #'' Eurybrachys rubroornata'' #'' Eurybrachys sanguinipes'' #'' Eurybrachys spinosa'' – type species (as ''Cicada spinosa'' ) #'' Eurybrachys tomentosa'' #'' Eury ...

Nymph (biology)
In biology, a nymph is the immature form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph's overall form already resembles that of the adult, except for a lack of wings (in winged species). In addition, while a nymph moults, it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars. This is the case, for example, in Orthoptera (crickets, grasshoppers and locusts), Hemiptera (cicadas, shield bugs, whiteflies, aphids, leafhoppers, froghoppers, treehoppers etc.), mayflies, termites, cockroaches, mantises, stoneflies and Odonata (dragonflies and damselflies). Nymphs of aquatic insects, as in the Odonata, Ephemeroptera, and Plecoptera, are also called naiads, an Ancient Greek name for mythological water nymphs. Usage of the term 'naiad' is no longer popular among entomologists, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australasia
Australasia is a region that comprises Australia, New Zealand and some neighbouring islands in the Pacific Ocean. The term is used in a number of different contexts, including geopolitically, physiogeographically, philologically, and ecologically, where the term covers several slightly different, but related regions. Derivation and definitions Charles de Brosses coined the term (as French ''Australasie'') in ''Histoire des navigations aux terres australes'' (1756). He derived it from the Latin for "south of Asia" and differentiated the area from Polynesia (to the east) and the southeast Pacific (Magellanica). In the late 19th century, the term Australasia was used in reference to the "Australasian colonies". In this sense it related specifically to the British colonies south of Asia: New South Wales, Queensland, South Australia, Tasmania, Western Australia, Victoria (i.e., the Australian colonies) and New Zealand. Australasia found continued geopolitical attention in the earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatomical Terms Of Location
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Ancyra (planthopper)
''Ancyra'' is a small genus of planthoppers of the family Eurybrachidae and the only genus in the tribe Ancyrini. Species in this genus occur in southeast Asia. Description Members of the genus are well known for having a pair of prolonged filaments at the tips of the forewings that arise near a pair of small glossy spots; this creates the impression of a pair of antennae, with corresponding "eyes" (a remarkable case of automimicry). The "false head" effect is further reinforced by the bugs' habit of walking backwards when it detects movement nearby, so as to misdirect predators to strike at its rear, rather than at its actual head. Taxonomy The genus ''Ancyra'' was first named in 1845 by Scottish zoologist Adam White. It is the only genus of the tribe Ancyrini (subfamily Platybrachinae, family Eurybrachidae). The type species is ''Ancyra appendiculata'', the species name meaning ''bearing appendages''. Species , lists the following seven species in the genus ''Ancyra'': *'' ...

Honeydew (secretion)
Honeydew is a sugar-rich sticky liquid, secreted by aphids and some scale insects as they feed on plant sap. When their mouthpart penetrates the phloem, the sugary, high-pressure liquid is forced out of the anus of the aphid. Honeydew is particularly common as a secretion in hemipteran insects and is often the basis for trophobiosis. Some caterpillars of Lycaenidae butterflies and some moths also produce honeydew. Honeydew producing insects, like cicadas, pierce phloem ducts to access the sugar rich sap. The sap continues to bleed after the insects have moved on, leaving a white sugar crust called manna. Ants may collect, or "milk", honeydew directly from aphids and other honeydew producers, which benefit from their presence due to their driving away predators such as lady beetles or parasitic wasps—see ''Crematogaster peringueyi''. Animals and plants in a mutually symbiotic arrangement with ants are called Myrmecophiles. In Madagascar, some gecko species in the genera ''Ph ...

Coccinellidae
Coccinellidae () is a widespread family of small beetles ranging in size from . They are commonly known as ladybugs in North America and ladybirds in Great Britain. Some entomologists prefer the names ladybird beetles or lady beetles as they are not true bugs. Many of the species have conspicuous aposematic colours and patterns, such as red with black spots, that warn potential predators that they are distasteful. The majority of the more than 6,000 described species are generally considered beneficial insects, because many prey on herbivorous hemipterans such as aphids or scale insects, which are agricultural pests. Many coccinellids lay their eggs directly in aphid and scale insect colonies, ensuring their larvae have an immediate food source. However, some species such as the herbivorous Mexican bean beetle are agricultural pests. Etymology The name ''coccinellids'', created by Pierre André Latreille, is derived from the Latin word ''coccineus'' meaning "scarlet". The na ...
