''Acraea esebria'', the dusky acraea, is a butterfly of the family Nymphalidae from southern and eastern Africa. Description The wingspan is 45–55 mm for males and 53–60 mm for females. Males and females both show the same range of colouration. The dusky acraea is a variable species, but the most common form is black with a white band across the forewing and a white patch on the lower forewing and on the hindwing.Williams, M. (1994). ''Butterflies of Southern Africa: A Field Guide''. Southern Book Publishers. . There are a number of described morphs (with white, yellow or orange patches) including: *f. ''ertli'' *f. ''esebria'' *f. ''protea'' (black with creamy-yellow patches) *f. ''monteironis'' (black with white patches) *f. ''jacksoni'' Description in Seitz The numerous forms of ''A. esebria'' differ especially in the colour of the light markings, in the breadth of the subapical band and the hindmarginal spot of the forewing and in the development of the dark m ...

William Chapman Hewitson
William Chapman Hewitson (9 January 1806, in Newcastle upon Tyne – 28 May 1878, in Oatlands Park, Surrey) was a British natural history, naturalist. A wealthy collector, Hewitson was particularly devoted to Coleoptera (beetles) and Lepidoptera (butterflies and moths) and, also, to Bird nest, birds' nests and Bird egg, eggs. His collection of butterflies, collected by him as well as purchased from travellers throughout the world, was one of the largest and most important of his time. He contributed to and published many works on entomology and ornithology and was an accomplished scientific illustrator. Life William Hewitson was educated in York. He became a Surveying, land-surveyor and was for some time employed under George Stephenson on the London and Birmingham Railway. Delicate health and the accession to an ample fortune through the death of a relative led him to give up his profession and he afterwards devoted himself to scientific studies. He lived for a time at Bristol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Urera Trinervis
''Urera trinervis'' ( Hochst.) Friis & Immelman is a softly woody dioecious liane, sometimes epiphytic, climbing to 20 m, often to the canopy and hanging in festoons. It is one of some 44 species of ''Urera'' belonging to the nettle family Urticaceae. It is known in English as the tree climbing-nettle or climbing nettle. Habitat and range Found up to 1600 m, this species is widely distributed in coastal forest, forest margins, and dune forest of the Eastern Cape (as far south as Port St Johns) and KwaZulu-Natal, in eastern Zimbabwe, north along the African east coast to Ethiopia, and across tropical Africa to Ghana. It is also known from Madagascar. Description Attaching by adventitious roots, its stems are up to 10 cm in diameter, are occasionally armed with stinging hairs and exude copious and clear potable sap when cut. Bark is grey to brownish-black and longitudinally striate with large leaf scars on young branches. Pith is spongy, or stems are hollow in centre. Leave ...

Urtica
''Urtica'' is a genus of flowering plants in the family Urticaceae. Many species have stinging hairs and may be called nettles or stinging nettles, although the latter name applies particularly to '' Urtica dioica''. ''Urtica'' species are food for the caterpillars of numerous Lepidoptera (butterflies and moths), such as the tortrix moth '' Syricoris lacunana'' and several Nymphalidae, such as '' Vanessa atalanta'', one of the red admiral butterflies. The generic name ''Urtica'' derives from the Latin for sting. Description ''Urtica'' species grow as annuals or perennial herbaceous plants, rarely shrubs. They can reach, depending on the type, location and nutrient status, a height of . The perennial species have underground rhizomes. The green parts have stinging hairs. Their often quadrangular stems are unbranched or branched, erect, ascending or spreading. Most leaves and stalks are arranged across opposite sides of the stem. The leaf blades are elliptic, lanceolate, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are im ...

Great Rift Valley, Kenya
The Great Rift Valley is part of an intra-continental ridge system that runs through Kenya from north to south. It is part of the Gregory Rift, the eastern branch of the East African Rift, which starts in Tanzania to the south and continues northward into Ethiopia. It was formed on the "Kenyan Dome" a geographical upwelling created by the interactions of three major tectonics: the Arabian, Nubian, and Somalian plates. In the past, it was seen as part of a "Great Rift Valley" that ran from Madagascar to Syria. Most of the valley falls within the former Rift Valley Province. The valley contains the Cherangani Hills and a chain of volcanoes, some of which are still active. The climate is mild, with temperatures usually below . Most rain falls during the March–June and October–November periods. The Tugen Hills to the west of Lake Baringo contain fossils preserved in lava flows from the period 14 to 4 million years ago. The relics of many hominids, ancestors of humans, have b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
