Harry Eltringham FRS (18 May 1873, South Shields – 26 November 1941, Stroud) was an English histologist and entomologist who specialised in Lepidoptera. Life He had been awarded a Master of Science (Cantab and Oxon) and a Doctor of Science (Oxon). He worked at the Hope Department of Entomology. He wrote ''Histological and Illustrative Methods for Entomologists'' , The Senses of Insects, London, Methuen (1933) and on Lepidoptera Nymphalidae: Subfamily Acraeinae. ''Lepidopterorum Catalogus'' 11:1-65 with Karl Jordan (1913) and On specific and mimetic relationships in the genus Heliconius.

Butterfly
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the Order (biology), order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily (zoology), superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo Holometabolism, complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nymphalidae
The Nymphalidae are the largest family of butterflies, with more than 6,000 species distributed throughout most of the world. Belonging to the superfamily Papilionoidea, they are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings.

Tanzania
Tanzania (; ), officially the United Republic of Tanzania ( sw, Jamhuri ya Muungano wa Tanzania), is a country in East Africa within the African Great Lakes region. It borders Uganda to the north; Kenya to the northeast; Comoro Islands and the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. Mount Kilimanjaro, Africa's highest mountain, is in northeastern Tanzania. According to the United Nations, Tanzania has a population of million, making it the most populous country located entirely south of the equator. Many important hominid fossils have been found in Tanzania, such as 6-million-year-old Pliocene hominid fossils. The genus Australopithecus ranged across Africa between 4 and 2 million years ago, and the oldest remains of the genus ''Homo'' are found near Lake Olduvai. Following the rise of '' Homo erectus'' 1.8 million years ago, humanity spread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paullinia Pinnata
''Paullinia pinnata'' is a flowering plant species in the genus of ''Paullinia'' found in South America and Africa. The long flexible stems of ''P. pinnata'' are used to poison fish in shallow pools, as described by the English naturalist Henry Walter Bates in his book ''The Naturalist on the River Amazons''. Chemistry The plant contains the ceramide paullinomide A, β-amyrin, steroids, the coumarinolignoid 2-(4-hydroxy-3,5-dimethoxyphenyl)-3-hydroxymethyl-2,3-dihydro-1,4,5-trioxaphenanthren-6-one, 5α-poriferastane-3ß,6α-diol and l-quebrachitol. It also contains the triterpenoids lupeyl steryl ether, 3-oxo-11α-hydroxyl-20(29)lupen and the lupeol-3-isovanniloyl ester paullinoyl (3-O-isovanilloyl-3R,5R,8R,9R,10R,13R,14S,17S,18R,19R-lup-20(29)-en), and the flavone glycosides diosmetin-7-O-(2‘ ‘-O-β-d-apiofuranosyl-6‘ ‘-acetyl-β-d-glucopyranoside) and tricetin-4‘-O-methyl-7-O-(2‘ ‘-O-β-d-apiofuranosyl-6‘ ‘-acetyl-β-d-glucopyranoside).Two New Flav ...

Alchornea Cordifolia
''Alchornea cordifolia'' is a shrub or small tree distributed throughout tropical Africa, it can grow up to 8 metres tall. The plant is used in traditional African medicine. Common name is the Christmas bush. Chemical constituents The leaves, roots and stem bark contain terpenoids, steroid glycosides, flavonoids, tannins, saponins, carbohydrates and the imidazopyrimidine alkaloids alchorneine, alchornidine, and several guanidine alkaloids. The leaves also contain a range of hydroxybenzoic acids: gallic acid and its ethyl ester, gentisic acid, anthranilic acid, protocatechuic acid, and ellagic acid (alizarine yellow). A C20 homolog of vernolic acid Vernolic acid (leukotoxin) is a long chain fatty acid that is monounsaturated and contains an epoxide. It is the R,R-''cis'' epoxide derived from the C12–C13 alkene of linoleic acid. Vernolic acid was first definitively characterized in 1954. I ... named alchornoic acid can be found in the seed oil.
