Eudicella Euthalia
''Eudicella euthalia'' is a tropical, east African species of flower beetle in the genus Eudicella, belonging to the subfamily Cetoniidae. Description ''Eudicella euthalia'' reaches about of length in the males, while the females are slightly smaller, reaching about of length. Head and pronotum are usually metallic green whilst the elytra are a pale to strong yellow with four dark black spots on each corner. The six legs are dark red in coloration. The male possesses a Y-shaped horn pointing upwards from the forehead, used in fighting other males for females and in defense of territory. This varies in size due to conditions and quality of habitat in the larval stage and hereditary genetics. The horn, like the legs. Is a ruddy red in coloration. Females lay eggs into a substrate of rotting leaf litter and wood, eggs that require about ten days to hatch in optimum habitat conditions. The development of larvae takes about five months, feeding on the substrate they are laid in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Museum (Prague)
The National Museum (NM) (Czech: ''Národní muzeum'') is a Czech museum institution intended to systematically establish, prepare, and publicly exhibit natural scientific and historical collections. It was founded in 1818 by Kašpar Maria Šternberg. Historian František Palacký was also strongly involved in the foundation of the museum. The National Museum houses nearly 14 million items from the areas of natural history, history, arts, music and librarianship, which are located in dozens of museum buildings. The main building of the National Museum has been renovated in 2011–2019, and permanent exhibitions are gradually being opened from Spring 2020. Origins After the French Revolution, royal and private collections of art, science and culture were made available to the public. The beginnings of the museum can be seen as far back as 1796 when the private Society of Patriotic Friends of the Arts was founded by Count Casper Sternberk-Manderschied and a group of other prominen ...

Henry Walter Bates
Henry Walter Bates (8 February 1825, in Leicester – 16 February 1892, in London) was an English naturalist and explorer who gave the first scientific account of mimicry in animals. He was most famous for his expedition to the rainforests of the Amazon with Alfred Russel Wallace, starting in 1848. Wallace returned in 1852, but lost his collection on the return voyage when his ship caught fire. When Bates arrived home in 1859 after a full eleven years, he had sent back over 14,712 species (mostly of insects) of which 8,000 were (according to Bates, but see Van Wyhe) new to science. Bates wrote up his findings in his best-known work, '' The Naturalist on the River Amazons''. Life Bates was born in Leicester to a literate middle-class family. However, like Wallace, T.H. Huxley and Herbert Spencer, he had a normal education to the age of about 13 when he became apprenticed to a hosiery manufacturer. He joined the Mechanics' Institute (which had a library), studied in his sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cetoniidae
Flower chafers are a group of scarab beetles, comprising the subfamily Cetoniinae. Many species are diurnal and visit flowers for pollen and nectar, or to browse on the petals. Some species also feed on fruit. The group is also called fruit and flower chafers, flower beetles and flower scarabs. There are around 4,000 species, many of them still undescribed. Twelve tribes are presently recognized: Cetoniini, Cremastocheilini, Diplognathini, Goliathini, Gymnetini, Phaedimini, Schizorhinini, Stenotarsiini, Taenioderini, Trichiini, Valgini, and Xiphoscelidini. The tribe Gymnetini is the biggest of the American tribes, and Goliathini contains the largest species, and is mainly found in the rainforest regions of Africa. Description Adult flower chafers are usually brightly coloured beetles, often metallic, and somewhat flattened in shape. The insertions of the antennae are visible from above, while the mandibles and labrum are hidden by the clypeus. The elytra lack a narrow ...

Pronotum
The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum ( dorsal), the prosternum ( ventral), and the propleuron ( lateral) on each side. The prothorax never bears wings in extant insects (except in some cases of atavism), though some fossil groups possessed wing-like projections. All adult insects possess legs on the prothorax, though in a few groups (e.g., the butterfly family Nymphalidae) the forelegs are greatly reduced. In many groups of insects, the pronotum is reduced in size, but in a few it is hypertrophied, such as in all beetles (Coleoptera). In most treehoppers (family Membracidae, order Hemiptera), the pronotum is expanded into often fantastic shapes that enhance their camouflage or mimicry. Similarly, in the Tetrigidae, the pronotum is extended backward to cover the flight wings, supplanting the function of the tegmina. See also * Glossary o ...

Elytra
An elytron (; ; , ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs ( Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes alternatively spelled as "hemielytra"), and in most species only the basal half is thickened while the apex is membranous, but when they are entirely thickened the condition is referred to as "coleopteroid". An elytron is sometimes also referred to as a shard. Description The elytra primarily serve as protective wing-cases for the hindwings underneath, which are used for flying. To fly, a beetle typically opens the elytra and then extends the hindwings, flying while still holding the elytra open, though many beetles in the families Scarabaeidae and Buprestidae can fly with the elytra closed (e.g., most Cetoniinae; ). In a number of groups, the elytra are reduced to various degrees, (e.g., the beetle families Staphylinidae and Ripiphoridae), o ...

Hereditary Genetics
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents. Through heredity, variations between individuals can accumulate and cause species to evolve by natural selection. The study of heredity in biology is genetics. Overview In humans, eye color is an example of an inherited characteristic: an individual might inherit the "brown-eye trait" from one of the parents. Inherited traits are controlled by genes and the complete set of genes within an organism's genome is called its genotype. The complete set of observable traits of the structure and behavior of an organism is called its phenotype. These traits arise from the interaction of its genotype with the environment. As a result, many aspects of an organism's phenotype are not inherited. For example, sunt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teneral
Ecdysis is the moulting of the cuticle in many invertebrates of the clade Ecdysozoa. Since the cuticle of these animals typically forms a largely inelastic exoskeleton, it is shed during growth and a new, larger covering is formed. The remnants of the old, empty exoskeleton are called exuviae. After moulting, an arthropod is described as ''teneral'', a ''callow''; it is "fresh", pale and soft-bodied. Within one or two hours, the cuticle hardens and darkens following a tanning process analogous to the production of leather. During this short phase the animal expands, since growth is otherwise constrained by the rigidity of the exoskeleton. Growth of the limbs and other parts normally covered by the hard exoskeleton is achieved by transfer of body fluids from soft parts before the new skin hardens. A spider with a small abdomen may be undernourished but more probably has recently undergone ecdysis. Some arthropods, especially large insects with tracheal respiration, expand thei ...

Rwanda
Rwanda (; rw, u Rwanda ), officially the Republic of Rwanda, is a landlocked country in the Great Rift Valley of Central Africa, where the African Great Lakes region and Southeast Africa converge. Located a few degrees south of the Equator, Rwanda is bordered by Uganda, Tanzania, Burundi, and the Democratic Republic of the Congo. It is highly elevated, giving it the soubriquet "land of a thousand hills", with its geography dominated by mountains in the west and savanna to the southeast, with numerous lakes throughout the country. The climate is temperate to subtropical, with two rainy seasons and two dry seasons each year. Rwanda has a population of over 12.6 million living on of land, and is the most densely populated mainland African country; among countries larger than 10,000 km2, it is the fifth most densely populated country in the world. One million people live in the capital and largest city Kigali. Hunter-gatherers settled the territory in the Stone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malawi
Malawi (; or aláwi Tumbuka: ''Malaŵi''), officially the Republic of Malawi, is a landlocked country in Southeastern Africa that was formerly known as Nyasaland. It is bordered by Zambia to the west, Tanzania to the north and northeast, and Mozambique to the east, south and southwest. Malawi spans over and has an estimated population of 19,431,566 (as of January 2021). Malawi's capital (and largest city) is Lilongwe. Its second-largest is Blantyre, its third-largest is Mzuzu and its fourth-largest is its former capital, Zomba. The name ''Malawi'' comes from the Maravi, an old name for the Chewa people who inhabit the area. The country is nicknamed "The Warm Heart of Africa" because of the friendliness of its people. The part of Africa now known as Malawi was settled around the 10th century by migrating Bantu groups . Centuries later, in 1891, the area was colonised by the British and became a protectorate of the United Kingdom known as Nyasaland. In 1953, it b ...
