Flatida Rosea
''Flatida rosea'', the flower-spike bug or the flatid leaf bug, is a species of planthopper in the family Flatidae. It is found in Madagascar dry deciduous forests, tropical dry forests in Madagascar, and the adult insects are gregarious, the groups orienting themselves in such a way that they resemble a flower spike. The adults have wide pink wings which they hold vertically in a tent-like fashion, concealing the whole body. The nymphs have no wings, but can move about, and are defensively covered in wispy white wax, with a plume of waxy tendrils. Like other bugs in this family, both adults and nymphs feed by piercing the bark with their mouthparts and sucking sap from the phloem. The adults are mobile, and can jump if disturbed. ''Flatida rosea'' feed on the liana ''Elachyptera minimiflora''. The Nymph (biology), nymphs produce copious quantities of Honeydew (secretion), honeydew and the Coquerel's coua (''Coua coquerelii'') feeds on this. References External links * ...

Leopold Melichar
Leopold Melichar (5 December 1856 – 2 September 1924) was a Moravian entomologist and physician who specialized in the taxonomy of the leafhoppers. Melichar was born in Brno, Moravia and studied medicine in Prague before beginning practice in Vienna from 1888. He became an official in the ministry of health and in his spare time he took an interest in insects. Through the influence of Ladislav Duda he began to specialize in the leafhoppers, examining the collections of Uzel Uzel (; or Uzel-près-l'Oust) is a commune in the Côtes-d'Armor department in Brittany in northwestern France. It is about west-northwest of Rennes and north-northwest of Loudéac. The old school, in the centre of Uzel, was the scene of tor ... from Sri Lanka. Melichar returned to live in Brno in 1912 and during World War I he headed the local Red Cross Hospital. Melichar also collected in North Africa, Spain and around the Mediterranean and his collections were bequeathed to the Moravian Museum. Mo ...

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 ...

Flatidae
Flatidae are a family of fulgoroid planthoppers. They are cosmopolitan in distribution and are distinguished from others in the superfamily by a combination of characters. Like all other planthoppers, they suck phloem sap of plants. Some species are known to communicate with vibrations through the plant stems. Communication may be with mates, or with ants that tend the nymphs, protecting them and gathering honeydew secretions. Adults of some species have brightly coloured forewings which are tougher and known as tegmina unlike the membranous hindwings which are used for flight. Although a few can be identified by their coloration, most species requires dissection and examination under a microscope with access to literature on already described species. There are two sub-families within the family. In the subfamily Flatinae, the body of adults is flattened laterally and the tegmina are tent-like. In the Flatoidinae, the body is not laterally compressed and the tegmina are not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar Dry Deciduous Forests
The Madagascar dry deciduous forests represent a tropical dry forest ecoregion situated in the western and northern part of Madagascar. The area has high numbers of endemic plant and animal species but has suffered large-scale clearance for agriculture. They are among the world's richest and most distinctive dry forests and included in the Global 200 ecoregions by the World Wide Fund. The area is also home to distinctive limestone karst formations known as tsingy, including the World Heritage Site of Bemaraha. Geography There are two separate areas within the ecoregion: the western side of Madagascar from the Ampasindava peninsula in the north to Belo-sur-Tsiribihina and Maromandia in the south (this is most of Mahajanga Province); and the northern tip of the island (apart from the high areas of Amber Mountain). Geological substrate is varied and includes the tsingy limestone massifs. These dry deciduous forests span the coastal plain with its limestone plateaus emanatin ...

Phloem
Phloem (, ) is the living biological tissue, tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as ''photosynthates'', in particular the sugar sucrose, to the rest of the plant. This transport process is called translocation. In trees, the phloem is the innermost layer of the bark (botany), bark, hence the name, derived from the Ancient Greek word (''phloiós''), meaning "bark". The term was introduced by Carl Nägeli in 1858. Structure Phloem tissue consists of conducting Cell (biology), cells, generally called sieve elements, Ground tissue#Parenchyma, parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells and supportive cells, such as fibres and sclereids. Conducting cells (sieve elements) Sieve elements are the type of cell that are responsible for transporting sugars throughout the plant. At maturity they lack a Cell nucleus, nucleus and have very few organelles, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
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 ...

Coquerel's Coua
Coquerel's coua (''Coua coquereli'') is a species of cuckoo in the family Cuculidae. It is Endemism, endemic to Madagascar. Its habitat is subtropical or tropical dry forests. It was named in 1867 by the French naturalist Alfred Grandidier in honor of the French navy surgeon and naturalist Charles Coquerel. Description Coquerel's coua is approximately in length and has a large blue patch of bare skin around the eye, a characteristic of the ''Coua'' genus that is similar to African turacos. The plumage is silky, the crown is black, the upper parts and tail are light brown or greyish-brown, and the lower breast and belly is suffused with red. The iris is red and the beak and legs are slaty grey. As a member of the cuckoo family, it has a reversible third toe and resembles the coucal in its method of scrambling through tangled bushes and lianas while searching for food. Observations indicate that it can climb about above the ground. Distribution and habitat Coquerel's coua is Ende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Of Madagascar
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
