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 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 nymphs produce copious quantities of honeydew and the Coquerel's coua Coquerel's coua (''Coua coquereli'') is a species of cuckoo in the family Cuculidae. It is Endemism, endemic to Madagascar.

Leopold Melichar
Leopold Melichar (5 December 1856 – 2 September 1924) was a Moravian entomologist and physician who specialized in the taxonomy of the Cicadellidae, 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 Jindřich Uzel, Uzel 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. Most of the taxa described by Melichar were based on external morphology and did not involve examination of the genitalia.

1901
December 13 of this year is the beginning of signed 32-bit Unix time, and is scheduled to end in January 19, 2038. Summary Political and military 1901 started with the unification of multiple British colonies in Australia on January 1 to form the Commonwealth of Australia after a referendum in 1900, Subsequently, the 1901 Australian election would see the first Australian prime minister, Edmund Barton. On the same day, Nigeria became a British protectorate. Following this, the Victorian Era would come to a end after Queen Victoria died on January 22 after a reign of 63 years and 216 days, which was longer than those of any of her predecessors, Her son, Edward VII, succeeded her to the throne. Events January * January 1 ** The British colonies of New South Wales, Queensland, South Australia, Tasmania, Victoria and Western Australia federate as the Commonwealth of Australia; Edmund Barton becomes the first Prime Minister of Australia. ** Nigeria become ...

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 few are considered pests. Fulgoromorphs 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 the body and part of the legs. Nymphs of many planthoppers produce wax from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flatidae
Flatidae are a family of fulgoroid planthoppers. They are Cosmopolitan distribution, 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 (secretion), honeydew secretions. Adults of some species have brightly coloured forewings which are tougher and known as Tegmen, 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 subfamilies within the family. In the subfamily Flatinae, the body of adults is flattened laterally and the tegmina are tent-like. In the Flatoidinae, the bod ...

Madagascar Dry Deciduous Forests
The Madagascar dry deciduous forests represent a tropical and subtropical dry broadleaf forests, tropical dry forest ecoregion situated in the western and northern part of Madagascar. The area has high numbers of Endemism, 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 for Nature, World Wide Fund. The area is also home to distinctive limestone karst formations known as Karst topography, tsingy, including the World Heritage Site of Tsingy de Bemaraha Strict Nature Reserve, 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 National Park, Amber Mount ...

Phloem
Phloem (, ) is the living 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, hence the name, derived from the Ancient Greek word (''phloiós''), meaning "bark". The term was introduced by Carl Nägeli in 1858. Different types of phloem can be distinguished. The early phloem formed in the growth apices is called protophloem. Protophloem eventually becomes obliterated once it connects to the durable phloem in mature organs, the metaphloem. Further, secondary phloem is formed during the thickening of stem structures. Structure Phloem tissue consists of conducting cells, generally called sieve elements, parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells and supportive cells, such ...

Nymph (biology)
In biology, a nymph (from Ancient Greek wikt:νύμφα, νύμφα ''nūmphē'' meaning "bride") is the juvenile (organism), juvenile form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (biology), 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) and the emergence of genitalia. In addition, while a nymph ecdysis, moults, it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars. Taxa with nymph stages Many species of Arthropod, arthropods have nymph stages. This includes the insect orders such as Orthoptera (cricket (insect), crickets, grasshoppers and locusts), Hemiptera (cicadas, shield bugs, Whitefly, whiteflies, aphids, leafhoppers, froghoppers, treehoppers), mayfly, mayflies, termites, cockroaches, mantises, ...

Honeydew (secretion)
Honeydew is a sugar-rich sticky liquid, secreted by aphids, some scale insects, and many other true bugs and some other 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 insects, allowing them to rapidly process the large volume of sap required to extract essential nutrients present at low concentrations. 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. In addition to various sugars, honeydew contains small amounts of amino acids, other organic compounds, and inorganic Salt (chemistry), salts with its precise makeup affected by factors such as insect species, host plant species, and whether a symbiotic organism is present. Honeydew-producing insects, like cicadas, pierce phloem ducts to access the sugar rich sap; the excess fluid released by ci ...

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 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 a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a brain and a ventral nerve cord. Most insects reproduce by laying eggs. Insects breathe air through a system of paired openings along their sides, connected to small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in vessels, and some circulates in an open hemocoel. Insect vision is mainly through their compound eyes, with additional small ocelli. Many insects can hear, using tympanal organs, which may be on the legs or other parts of the body. The ...
