Phyllonorycter Grewiaephilos
''Phyllonorycter grewiaephilos'' is a moth of the family Gracillariidae. It is found in the Rift Valley and Tsavo National Park in Kenya. The habitat consists of savannah areas at altitudes between 470 and 920 meters. The length of the forewings is 2.7–2.9 mm. The forewings are elongate and the ground colour is ochreous brown with white markings. The hindwings are dirty white with a slight golden shine. Adults are on wing from early February to mid-April. The larvae feed as leaf miners on ''Grewia villosa''. The mine has the form of a tentiform mine, which is either elongate or oval. It is made on the underside of the leaf. The mine is 11–16 mm long and opaque creamy or light brown in colour. The frass is loosely scattered. Pupation takes place without cocoon. Etymology The specific name is composed of the host plant genus ''Grewia ''Grewia'' is a large flowering plant genus in the mallow family Malvaceae, in the expanded sense as proposed by the Angiosperm ...

Moth
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995.

Gracillariidae
Gracillariidae is an important family of insects in the order Lepidoptera and the principal family of leaf miners that includes several economic, horticultural or recently invasive pest species such as the horse-chestnut leaf miner, ''Cameraria ohridella''. Taxonomy and systematics There are 98 described genera of Gracillariidae (see below). A complete checklist is available of all currently recognised species. There are many undescribed species in the tropics but there is also an online catalogue of Afrotropical described speci the South African fauna is quite well known. Although Japanese and Russian authors have recognised additional subfamilies, there are three currently recognised subfamilies, Phyllocnistinae of which is likely to be basal. In this subfamily, the primitive genus ''Prophyllocnistis'' from Chile feeds on the plant genus '' Drimys'' (Winteraceae), and has leaf mines structurally similar in structure to fossils (see "Fossils"). While there have been some rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tsavo Conservation Area
The Tsavo Conservation Area (sometimes referred to as the Tsavo Ecosystem) is a complex of protected and other wildlife areas in southern Kenya and north-eastern Tanzania. It is composed of Tsavo East National Park, Tsavo West National Park, Chyulu Hills National Park, South Kitui National Reserve, ranches in Galana, Taita, Kulalu and Amboseli and adjacent private and communal lands. Bordering Mkomazi National Park in Tanzania, the Tsavo Conservation Area comprises an area of around 42,000 km2, of which over 25,000 km2 is protected. The protected portion in Kenya represent almost half of the country's protected areas. The wider conservation area harbours Kenya's largest elephant population, at 40% of Kenya's total elephant population, as well as 18% of Kenya's black rhino population, much of which live in the Ngulia Rhino Sanctuary. There are indications that the elephant population is expanding at a rate of 4-5% per annum, however there is concern that poaching remains a ...

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 immobil ...

Leaf Miner
A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. The vast majority of leaf-mining insects are moths (Lepidoptera), sawflies (Symphyta, the mother clade of wasps), and flies (Diptera). Some beetles also exhibit this behavior. Like woodboring beetles, leaf miners are protected from many predators and plant defenses by feeding within the tissues of the leaves, selectively eating only the layers that have the least amount of cellulose. When attacking ''Quercus robur'' (English oak), they also selectively feed on tissues containing lower levels of tannin, a deterrent chemical produced in great abundance by the tree. The pattern of the feeding tunnel and the layer of the leaf being mined is often diagnostic of the insect responsible, sometimes even to species level. The mine often contains frass, or droppings, and the pattern of frass deposition, mine shape, and host plant identity are useful to determi ...

Grewia Villosa
''Grewia villosa'' is a shrub, often scrambling and hardly exceeding 4 m in height. Leaves are fairly large, serrated and heart-shaped. It grows naturally, mainly in dry habitats. It is common in most of the semi-arid parts of Eastern Africa but may now be rare in parts of its natural distribution. It can be seen in Ein Gedi oasis in Israel, and in South Africa, where it is common. Its ripe copper-coloured fruits are eaten in East Africa. Uses The fruit of the ''Grewia villosa'' were eaten both while immature and green and also once they had ripened and hardened to a dark, reddish-brown. The bark was stripped off and crushed in water or chewed to a pulp which was used to wash the body as well as to clean the hair and disinfect the scalp See also * List of Southern African indigenous trees References *Maundu, P.

Frass
Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the German word ''Fraß'', which means the food takeup of an animal.M. Clark and O. Thyen. The Oxford-Duden German Dictionary. Publisher: Oxford University Press 1999. The English usage applies to excreted residues of anything that insects had eaten, and similarly, to other chewed or mined refuse that insects leave behind. It does not generally refer to fluids such as honeydew, but the point does not generally arise, and is largely ignored in this article. Such usage in English originated in the mid-nineteenth century at the latest. Modern technical English sources differ on the precise definition, though there is little actual direct contradiction on the practical realities. One glossary from the early twentieth century speaks of "...excrem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grewia
''Grewia'' is a large flowering plant genus in the mallow family Malvaceae, in the expanded sense as proposed by the Angiosperm Phylogeny Group. Formerly, Grewia was placed in either the family Tiliaceae or the Sparrmanniaceae. However, these were both not monophyletic with respect to other Malvales - as already indicated by the uncertainties surrounding placement of ''Grewia'' and similar genera - and have thus been merged into the Malvaceae. Together with the bulk of the former Sparrmanniaceae, ''Grewia'' is in the subfamily Grewioideae and therein the tribe Grewieae, of which it is the type genus. The genus was named by Carl Linnaeus, in honor of the botanist Nehemiah Grew (1641-1712) from England. Grew was one of the leading plant anatomists and microscope researchers of his time, and his study of pollen laid the groundwork for modern-day palynology. Ecology and uses Several Lepidoptera caterpillars are found to feed on ''Grewia'' species. These include the common nawab ( ...

Endemic Moths Of Kenya
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
