Schizodactylus Monstrosus
''Schizodactylus monstrosus'' or the maize cricket, is a species of large, robust cricket found in Asia, belonging to the family Schizodactylidae. It is found mainly in sandy habitats along rivers, and has large flattened tarsal extensions and wings that are curled at the tip, right above the cerci. They are nocturnal and show a high degree of variation in activity during the day and night. They hide in burrows that they dig on their own during the day. Description ''S. monstrosus'' adults are approximately 4 cm long, with the coloration being typical of that of a nocturnal or burrowing insect, an overall light yellow with black sections on the back and a lighter green on the belly. They have long, filiform antennae extending longer than their body, with the scape being white with a black dot and the rest of the antennae brown. The wings of ''S. monstrosus''are longer than the body and spiral up at the ends, over the cerci, when at rest. The labrum is large and covers the ...

Schizodactylidae
Schizodactylidae is a family of orthopteran insects found in Asia and southern Africa, known as dune crickets or splay-footed crickets. They are usually found in desert and sandy areas. Species are predatory, including ''Schizodactylus inexspectatus''. T. B. Fletcher notes that one captive individual did not feed on any vegetable matter. Fossils are known since the Early Cretaceous. Taxonomy One extinct and two extant genera in the subfamily Schizodactylinae are included: ;''† Brauckmannia'' Martins-Neto, 2007 * monotypic †''B. groeningae'' Martins-Neto, 2007 Crato Formation, Brazil, Early Cretaceous (Aptian) ;'' Comicus'' Brunner von Wattenwyl, 1888 * '' Comicus capensis'' Brunner von Wattenwyl, 1888 - type species ''Schizodactylus'' Authority: Brullé, 1835; distribution: mainland Asia # '' Schizodactylus brevinotus'' Ingrisch, 2002 # ''Schizodactylus burmanus'' Uvarov, 1935 # ''Schizodactylus hesperus'' Bei-Bienko, 1967 # ''Schizodactylus inexspectatus'' (Werner, F., 19 ...

Dru Drury
Dru Drury (4 February 1724 – 15 December 1803) was a British collector of natural history specimens and an entomologist. He had specimens collected from across the world through a network of ship's officers and collectors including Henry Smeathman. His collections were utilized by many entomologists of his time to describe and name new species and is best known for his book ''Illustrations of natural history'' which includes the names and descriptions of many insects, published in parts from 1770 to 1782 with copperplate engravings by Moses Harris. Life Dru Drury was born in Lad Lane, Wood Street, London where his father, also Dru [also given as "Drew"] Drury (1688–1763), was a Freedom of the City of London, citizen, goldsmith and silversmith of the City of London, and his second wife Mary, daughter of Dr Hesketh, chaplain to Anne, Queen of Great Britain, Queen Anne. The elder Dru Drury's grandfather, William, Lord of the Manor of Colne, Cambridgeshire, Colne (Drurys mano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nymph (biology)
In biology, a nymph is the immature form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph's overall form already resembles that of the adult, except for a lack of wings (in winged species). In addition, while a nymph moults, it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars. This is the case, for example, in Orthoptera (crickets, grasshoppers and locusts), Hemiptera (cicadas, shield bugs, whiteflies, aphids, leafhoppers, froghoppers, treehoppers etc.), mayflies, termites, cockroaches, mantises, stoneflies and Odonata (dragonflies and damselflies). Nymphs of aquatic insects, as in the Odonata, Ephemeroptera, and Plecoptera, are also called naiads, an Ancient Greek name for mythological water nymphs. Usage of the term 'naiad' is no longer popular among entomologists, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arunachal Pradesh
Arunachal Pradesh (, ) is a state in Northeastern India. It was formed from the erstwhile North-East Frontier Agency (NEFA) region, and became a state on 20 February 1987. It borders the states of Assam and Nagaland to the south. It shares international borders with Bhutan in the west, Myanmar in the east, and a disputed border with China in the north at the McMahon Line. Itanagar is the state capital of Arunachal Pradesh. Arunachal Pradesh is the largest of the Seven Sister States of Northeast India by area. Arunachal Pradesh shares a 1,129 km border with China's Tibet Autonomous Region. As of the 2011 Census of India, Arunachal Pradesh has a population of 1,382,611 and an area of . It is an ethnically diverse state, with predominantly Monpa people in the west, Tani people in the centre, Mishmi and Tai people in the east, and Naga people in the southeast of the state. About 26 major tribes and 100 sub-tribes live in the state. The main tribes of the state are Adi, Nyshi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Senescence
Senescence () or biological aging is the gradual deterioration of functional characteristics in living organisms. The word ''senescence'' can refer to either cellular senescence or to senescence of the whole organism. Organismal senescence involves an increase in death rates and/or a decrease in fecundity with increasing age, at least in the latter part of an organism's life cycle. Senescence is the inevitable fate of almost all multicellular organisms with germ-soma separation, but it can be delayed. The discovery, in 1934, that calorie restriction can extend lifespan by 50% in rats, and the existence of species having negligible senescence and potentially immortal organisms such as '' Hydra'', have motivated research into delaying senescence and thus age-related diseases. Rare human mutations can cause accelerated aging diseases. Environmental factors may affect aging – for example, overexposure to ultraviolet radiation accelerates skin aging.

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...

Cricket (insect)
Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. In older literature, such as Imms,Imms AD, rev. Richards OW & Davies RG (1970) ''A General Textbook of Entomology'' 9th Ed. Methuen 886 pp. "crickets" were placed at the family level (''i.e.'' Gryllidae), but contemporary authorities including Otte now place them in the superfamily Grylloidea. The word has been used in combination to describe more distantly related taxa in the suborder Ensifera, such as king crickets and mole crickets. Crickets have mainly cylindrically-shaped bodies, round heads, and long antennae. Behind the head is a smooth, robust pronotum. The abdomen ends in a pair of long cerci; females have a long, cylindrical ovipositor. Diagnostic features include legs with 3-segmented tarsi; as with many Orthoptera, the hind legs have enlarged femora, providing power for jumping. The front wings are adapted as tough, leathery elytra, and some crickets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grasshopper
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are among what is possibly the most ancient living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. Grasshoppers are typically ground-dwelling insects with powerful hind legs which allow them to escape from threats by leaping vigorously. As hemimetabolous insects, they do not undergo complete metamorphosis; they hatch from an egg into a nymph or "hopper" which undergoes five moults, becoming more similar to the adult insect at each developmental stage. The grasshopper hears through the tympanal organ which can be found in the first segment of the abdomen attached to the thorax; while its sense of vision is in the compound eyes, the change in light intensity is perceived in the simple eyes (ocelli). At high population densities and under certain environmental conditions, some grasshopper species can change color and behavior and form swarms. Under ...

Ground Beetle
Ground beetles are a large, cosmopolitan distribution, cosmopolitan family (biology), family of beetles, the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. As of 2015, it is one of the 10 most species-rich animal families. They belong to the Adephaga. Members of the family are primarily carnivorous, but some members are phytophagous or omnivorous. Description and ecology Although their body shapes and coloring vary somewhat, most are shiny black or metallic and have ridged wing covers (elytra). The elytra are fused in some species, particularly the large Carabinae, rendering the beetles unable to fly. The species ''Mormolyce phyllodes'' is known as violin beetle due to their peculiarly shaped elytra. All carabids except the quite primitive flanged bombardier beetles (Paussinae) have a groove on their arthropod leg, fore leg tibiae bearing a comb of hairs used for cleaning their antenna (biology), antennae. ...

Cannibalism
Cannibalism is the act of consuming another individual of the same species as food. Cannibalism is a common ecological interaction in the animal kingdom and has been recorded in more than 1,500 species. Human cannibalism is well documented, both in ancient and in recent times. The rate of cannibalism increases in nutritionally poor environments as individuals turn to members of their own species as an additional food source.Elgar, M.A. & Crespi, B.J. (1992) ''Cannibalism: ecology and evolution among diverse taxa'', Oxford University Press, Oxford ngland New York. Cannibalism regulates population numbers, whereby resources such as food, shelter and territory become more readily available with the decrease of potential competition. Although it may benefit the individual, it has been shown that the presence of cannibalism decreases the expected survival rate of the whole population and increases the risk of consuming a relative. Other negative effects may include the increased r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Bainbrigge Fletcher
Thomas Bainbrigge Fletcher (25 March 1878 – 30 April 1950) was an English entomologist. Although an amateur lepidopterist who worked in the Royal Navy, he became an expert on "microlepidoptera" and was appointed as the second Imperial Entomologist in India to succeed Harold Maxwell Lefroy. Although only an amateur entomologist, he is credited with reorganizing entomological research in India by coordinating and directing research, efficient sharing of findings and a reduction in duplication of research work. Fletcher's father William Bainbrigge Fletcher was a fleet surgeon in the Royal Navy (retired 1890). Thomas became a naval paymaster until he retired in 1915. While in the navy, he joined the Percy Sladen Trust Expedition to the Indian Ocean and was appointed Imperial Entomologist in India, succeeding Harold Maxwell-Lefroy at the Imperial Agricultural Research Institute at Pusa. Although lacking academic qualifications in entomology, he was a meticulous naturalist and v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schizodactylus Inexspectatus
''Schizodactylus inexspectatus'' (often misspelled "''inexpectatus''") is a species of dune cricket (Schizodactylidae) endemic to sand dunes of Çukurova and Göksu Deltas, Turkey. Taxonomic history ''Schizodactylus inexspectatus'' was first described by Franz Werner in 1901 under the name ''Comicus inexspectatus''. It was transferred to the genus ''Schizodactylus'' in 1931. The species was known from only a single individual and was not found again for almost a century, with the species generally thought to be extinct, but it was rediscovered in the Çukurova Delta after almost a century. Description and life history Adults reach long, and are yellow in colour, with black patches on the pronotum that resemble a butterfly. The cephalon and thorax representing more of the length than the abdomen. The antennae are long. The adults have short wings, approximately long, but they are incapable of flight. There are nine nymphal stages before adulthood, the first of which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
