Pseudacraea Kuenowi
''Pseudacraea kuenowii'', or Kuenow's false acraea, is a butterfly in the family Nymphalidae. It is found in Nigeria, Cameroon, Gabon, the Republic of the Congo, Angola, the Democratic Republic of the Congo, Kenya, Uganda and Zambia. Description ''Ps. kuenowi'' strongly recalls '' Ps. hobleyi'' in the orange transverse band of the forewing and the white median hand of the hindwing, but has in the basal part of the forewing instead of the black dots a thick black longitudinal streak in the cell and in 1 b. * ''kuenowi'' Dew.

Ogooué River
The Ogooué (or Ogowe), also known as the Nazareth river, some long, is the principal river of Gabon in west central Africa and the fifth largest river in Africa by volume of discharge, trailing only the Congo, Kasai, Niger and Zambezi. Its watershed drains nearly the entire country of Gabon, with some tributaries reaching into the Republic of the Congo, Cameroon, and Equatorial Guinea. Course The source of the Ogooué River was discovered in 1894 by Mary Kingsley, an English explorer who travelled up the banks by steamboat and canoe. The river rises in the northwest of the Bateke Plateaux near Kengue, Republic of Congo. It runs northwest, and enters Gabon near Boumango. Poubara Falls are near Maulongo. From Lastoursville up to Ndjole, the Ogooué is non-navigable due to rapids. From the latter city, it runs west, and enters the Gulf of Guinea near Ozouri, south of Port Gentil. The Ogowe Delta is quite large, about 100 km long and 100 km wide. Basin Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uganda
}), is a landlocked country in East Africa. The country is bordered to the east by Kenya, to the north by South Sudan, to the west by the Democratic Republic of the Congo, to the south-west by Rwanda, and to the south by Tanzania. The southern part of the country includes a substantial portion of Lake Victoria, shared with Kenya and Tanzania. Uganda is in the African Great Lakes region. Uganda also lies within the Nile basin and has a varied but generally a modified equatorial climate. It has a population of around 49 million, of which 8.5 million live in the capital and largest city of Kampala. Uganda is named after the Buganda kingdom, which encompasses a large portion of the south of the country, including the capital Kampala and whose language Luganda is widely spoken throughout the country. From 1894, the area was ruled as a protectorate by the United Kingdom, which established administrative law across the territory. Uganda gained independence from the UK on 9 Oc ...

Limenitidinae
The Limenitidinae are a subfamily of butterflies that includes the admirals and relatives. The common names of many species and genera reference military ranks or – namely the Adoliadini – titles of nobility (e.g., count, duke, earl, and marquis), in reference to these butterflies' large size, bold patterns, and dashing flight. In particular, the light stripe running lengthwise across the wings of many Limenitidini has reminded earlier authors of officers' (e.g. admiral, commander, commodore) shoulder marks and epaulets. In flight, many of these butterflies have the habit of flapping their wings, so the (usually) bright upperside and the cryptic underside alternate for the observer, then gliding for prolonged distances, with the motionless wings held outstretched. The common names of some Limenitidinae – "aeroplanes", "clippers", or " gliders" – refer to this flight pattern. Systematics The Biblidinae are sometimes merged here. The present subfamily is also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterflies Described In 1879
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large 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 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 out, and after its wings have expanded and dried, ...

Mimicry
In evolutionary biology, mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry functions to protect a species from predators, making it an anti-predator adaptation. Mimicry evolves if a receiver (such as a predator) perceives the similarity between a mimic (the organism that has a resemblance) and a model (the organism it resembles) and as a result changes its behaviour in a way that provides a selective advantage to the mimic. The resemblances that evolve in mimicry can be visual, acoustic, chemical, tactile, or electric, or combinations of these sensory modalities. Mimicry may be to the advantage of both organisms that share a resemblance, in which case it is a form of mutualism; or mimicry can be to the detriment of one, making it parasitic or competitive. The evolutionary convergence between groups is driven b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acraea Elongata
''Bematistes elongata'', the elongate bematistes, is a butterfly in the family Nymphalidae. It is found in Nigeria, Cameroon, Gabon, the Republic of the Congo and the Democratic Republic of the Congo. Description ''P. elongata'' Btlr. (58 b, c) is an easily recognized species with the sexes marked almost alike. In the male the ground-colour is dark black-brown above with a brown-yellow transverse band only about 4 mm. in breadth, which reaches the hindmargin and is but little curved; its spots are rather deeply cleft distally. The hindwing is dark black-brown in the basal part almost to the middle and has there a red-brown transverse band about 10 mm. in breadth at vein 2 and narrowing anteriorly, which is completely intersected by the black veins and streaks between the veins; the black marginal band is sharply defined, but at the apex only 2mm. in breadth and gradually narrowed posteriorly; the under surface of the hindwing is uniform smoke-brown and the black streaks nearly ...

Acraea Poggei
''Bematistes poggei'' is a butterfly in the family Nymphalidae. It is found in Zambia, Angola, the Democratic Republic of the Congo, Tanzania, Sudan, Uganda, Kenya, Tanzania and Ethiopia. Description ''P. poggei'' Dew. (58 d). The sexes are similarly coloured and marked; the ground-colour of the upper surface is nearly black; the transverse band of the forewing is light orange-yellow, 10-15mm. in breadth, on the distal side more or less convex, towards the base out off obliquely so that its proximal boundary-line is placed almost vertically to the costal margin; its spot in cellule 2 is obliquely cut off and almost reaches the base of vein 3; in the base of cellule 3 a small rounded black spot; the transverse band reaches to the hindmargin and in cellules 1 -2 usually also to the distal margin; the median band of the hindwing is white, sharply defined and 8-10 mm. in breadth; the sharply prominent black marginal band is consequently 6-10 mm. in breadth; the basal area of the hin ...

Pseudacraea Eurytus
''Pseudacraea eurytus'', the false wanderer, is a butterfly of the family Nymphalidae. It is found in Africa. Description The numerous forms of this group dolomena'' and ''Pseudacraea rubrobasalis">rubrobasalis''may be known at once by the long, distinct black streaks on the interneural folds of the hindwing; forewing always with 5 rounded black spots in the cell and 1 or 2 at the base of cellule 1b. The butterflies stand in interesting but very complicated mimetic relations with the ''Planema'' species which fly together with them. In the males the forewing is more pointed with the distal margin straight or slightly in the females the forewing very obtusely rounded with the distal margin curved. * ''Ps. eurytus'' L. (46 c). The hindmarginal spot of the forewing is large, reaches vein 3 and has its proximal edge sharp and straight, but does not cover the base of cellules 1b and 2; hindwing beneath at the base reddish, in the male above red-yellow, towards the distal margin g ...

Zambia
Zambia (), officially the Republic of Zambia, is a landlocked country at the crossroads of Central, Southern and East Africa, although it is typically referred to as being in Southern Africa at its most central point. Its neighbours are the Democratic Republic of the Congo to the north, Tanzania to the northeast, Malawi to the east, Mozambique to the southeast, Zimbabwe and Botswana to the south, Namibia to the southwest, and Angola to the west. The capital city of Zambia is Lusaka, located in the south-central part of Zambia. The nation's population of around 19.5 million is concentrated mainly around Lusaka in the south and the Copperbelt Province to the north, the core economic hubs of the country. Originally inhabited by Khoisan peoples, the region was affected by the Bantu expansion of the thirteenth century. Following the arrival of European explorers in the eighteenth century, the British colonised the region into the British protectorates of Barotseland-No ...
