Gryllus Spinulosus
''Eugaster spinulosa'' is a species of bush-cricket from Morocco. It is known as the whistle cricket, because herdsmen would dry it and pull off its legs, in order to use the cricket as a whistle. After mating, the male of the species cannot mate again for ten days. ''Eugaster spinulosa'' was first described by Carl Linnaeus in his 1763 work ''Centuria Insectorum'', as ''Gryllus spinulosus''. The holotype had been collected from the "Barbary Coast" ( Morocco) in 1756, and was in Alexander Macleay's collection when he travelled to Sydney Sydney ( ) is the capital city of the state of New South Wales, and the most populous city in both Australia and Oceania. Located on Australia's east coast, the metropolis surrounds Sydney Harbour and extends about towards the Blue Mountain ... in 1826. It is the oldest dated specimen in the University of Sydney's Macleay Museum. Its label bears the text "A curious insect from Barbary, the only one known of its kind in England ...

Cornell University Press
The Cornell University Press is the university press of Cornell University; currently housed in Sage House, the former residence of Henry William Sage. It was first established in 1869, making it the first university publishing enterprise in the United States, but was inactive from 1884 to 1930. The press was established in the College of the Mechanic Arts (as mechanical engineering was called in the 19th century) because engineers knew more about running steam-powered printing presses than literature professors. Since its inception, The press has offered work-study financial aid: students with previous training in the printing trades were paid for typesetting and running the presses that printed textbooks, pamphlets, a weekly student journal, and official university publications. Today, the press is one of the country's largest university presses. It produces approximately 150 nonfiction titles each year in various disciplines, including anthropology, Asian studies, biologica ...

Orthoptera Of Africa
Orthoptera () is an order (biology), order of insects that comprises the grasshoppers, locusts, and cricket (insect), crickets, including closely related insects, such as the Tettigoniidae, bush crickets or katydids and wētā. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives. More than 20,000 species are distributed worldwide. The insects in the order have incomplete metamorphosis, and produce sound (known as a "stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The Tympanum (anatomy), tympanum, or ear, is located in the front Tibia (arthropod), tibia in crickets, mole crickets, and bush crickets or katydids, and on the first abdominal segment in the grasshoppers and locusts. These organisms use vibrations to locate other individuals. Grasshoppers and other orthopterans are able to fold their Insect wing, w ...

Alexander Macleay
Alexander Macleay (also spelt McLeay) MLC FLS FRS (24 June 1767 – 18 July 1848) was a leading member of the Linnean Society, a fellow of the Royal Society and member of the New South Wales Legislative Council. Life Macleay was born on Ross-shire, Scotland, eldest son of William Macleay, provost of Wick. Alexander had a classical education, before relocating to London and becoming a wine merchant with his business partner William Sharp – after whom his first son was named. In 1795 he was elected a fellow of the Linnean Society of London, also serving as its secretary, and was also appointed chief clerk in the prisoners of war office. When the office was linked with the Transport Board after war broke out, Macleay became head of the correspondence department and by 1806 secretary. The board was abolished in 1815, and Macleay retired on an annual pension, of £750. Macleay's chief natural history interest was entomology, principally lepidoptery, and he possessed the fines ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpha Taxonomy
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whistle
A whistle is an instrument which produces sound from a stream of gas, most commonly air. It may be mouth-operated, or powered by air pressure, steam, or other means. Whistles vary in size from a small slide whistle or nose flute type to a large multi-piped church organ. Whistles have been around since early humans first carved out a gourd or branch and found they could make sound with it. In prehistoric Egypt, small shells were used as whistles. Many present day wind instruments are inheritors of these early whistles. With the rise of more mechanical power, other forms of whistles have been developed. One characteristic of a whistle is that it creates a pure, or nearly pure, tone. The conversion of flow energy to sound comes from an interaction between a solid material and a fluid stream. The forces in some whistles are sufficient to set the solid material in motion. Classic examples are Aeolian tones that result in galloping power lines, or the Tacoma Narrows Bridge (the ...

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
