Harold Oldroyd
Harold Oldroyd (24 December 1913 – 3 September 1978) was a British entomologist. He specialised in the biology of flies, and wrote many books, especially popular science that helped entomology to reach a broader public. His ''The Natural History of Flies'' is considered to be the "fly Bible". Although his speciality was the Diptera, he acknowledged that they are not a popular topic: "Breeding in dung, carrion, sewage and even living flesh, flies are a subject of disgust...not to be discussed in polite society". It was Oldroyd who proposed the idea of hyphenating the names of true flies (Diptera) to distinguish them from other insects with "fly" in their names. Thus, the "house-fly", " crane-fly" and " blow-fly" would be true flies, while the "dragonfly", " scorpion fly" and so on belong to other orders. He also debunked the calculation that a single pair of house-flies, if allowed to reproduce without inhibitions could, within nine months, number 5.6 trillion individuals, enough t ...

Horse-fly
Horse flies and deer flies are true flies in the family Tabanidae in the insect Order (biology), order Diptera. The adults are often large and agile in flight. Only females bite land vertebrates, including humans, to hematophagy, obtain blood. They prefer to fly in sunlight, avoiding dark and shady areas, and are inactive at night. They are found all over the world except for some islands and the polar regions (Hawaii, Greenland, Iceland). Both horse flies and botflies (Oestridae) are sometimes referred to as gadflies. Adult horse flies feed on nectar and plant exudates; males have weak insect mouthparts, mouthparts, but females have mouthparts strong enough to puncture the skin of large animals. This is for the purpose of obtaining enough protein from blood to produce eggs. The mouthparts of females are formed into a stout stabbing organ with two pairs of sharp cutting blades, and a spongelike part used to lap up the blood that flows from the wound. The larvae are predaceous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, fourth largest island, the List of island countries, second-largest island country, and the List of countries and dependencies by area, 46th largest country overall. Its capital and List of cities in Madagascar, largest city is Antananarivo. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife of Madagascar, wildlife being endemic. The island has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachycera Genera
The Brachycera are a suborder of the order Diptera. It is a major suborder consisting of around 120 families. Their most distinguishing characteristic is reduced antenna segmentation. Description A summary of the main physical characteristics is: * Antenna size (with eight or fewer flagellomeres) is reduced. In many species the third segment, the flagellum, is fused, except from a bristle called the arista that is sticking out from the fused flagellum. The arista consist of no more than three segments called aristomeres. * The maxillary palp (an elongated appendage near the mouth) has two segments or fewer. * The back portions of the larval head capsule extend into the prothorax (the anterior part of the thorax, which bears the first pair of legs). * Two distinct parts make up of the larval mandible (lower jaw). * The epandrium and hypandrium of the genitalia are separated in males. * No premandible is present on the lower surface of the labrum (the roof of the mout ...

Diptera Of Africa
Flies are insects of the Order (biology), order Diptera, the name being derived from the Ancient Greek, Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing more than 150,000 species including horse-flies, crane flies, hoverflies, mosquitoes and others. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great manoeuvrability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the larval food-source and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Madagascar
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...
