Tetracanthagyna Plagiata
The giant hawker (''Tetracanthagyna plagiata'') or the gigantic riverhawker, is a species of dragonfly in the family Aeshnidae. It is found throughout Sundaland, having been recorded on Thailand, Peninsular Malaysia, Singapore, Sumatra, and Borneo. It is the type species for the genus ''Tetracanthagyna''. It is the heaviest of all living Odonata, and additionally are the second largest of all living Odonates by wingspan, second only to ''Megaloprepus caerulatus'' (Pseudostigmatidae). ''T. plagiata'' is additionally the largest living dragonfly, with a maximum wingspan of 163 millimeters, exceeding the wingspan of runner-up ''Petalura ingentissima'' at 162 millimeters. Taxonomy ''Tetracanthagyna plagiata'' was initially described by Charles Owen Waterhouse in 1877 under the name ''Gynacantha plagiata'', classifying it under the now-separate dragonfly genus '' Gynacantha'', the type locality was listed as Borneo. Robert McLachlan commented that his peer Edmond de Sélys Longcha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Owen Waterhouse
Charles Owen Waterhouse (19 June 1843 – 4 February 1917) was an English entomologist who specialised in Coleoptera. He was the eldest son of George Robert Waterhouse. Waterhouse was an Assistant Keeper at the Natural History Museum, London, British Museum (Natural History), London. He wrote the Buprestidae part of Frederick DuCane Godman and Osbert Salvin's ''Biologia Centrali-Americana'' (1889) and very many papers on the worldwide beetle collections of the museum, describing hundreds of new species. He was President of the Royal Entomological Society from 1907 until 1908, and was appointed ISO in the 1910 Birthday Honours. Waterhouse died in February 1917 at the age of 73.

Robert McLachlan (entomologist)
Robert McLachlan FRS (10 April 183723 May 1904) was an English entomologist specializing in the study of lacewings (Neuroptera) and caddisflies (Trichoptera). Life McLachlan was born in London on 10 April 1837, one of five children of Hugh McLachlan and Hannah (Thompson) McLachlan. His father was a successful manufacturer of ship chronometers. He lived his early life in Ongar, Essex, and was educated in Ilford at a private school where he developed a good knowledge of English, French and German. Due to a sizable inheritance, McLachlan was a man of independent means and devoted himself entirely to the study of entomology and other aspects of natural history. An initial interest in botany was prompted by a desire to understand the relationship between butterflies and their food plants. In 1855, after a broken engagement, McLachlan traveled to New South Wales, Australia and Shanghai, China to study and collect botanical materials. On his return to England he enlisted the help of ...

National Archives Of Singapore
The National Archives of Singapore (NAS) (Malay: ''Arkib Negara Singapura'', Mandarin: 新加坡国家档案馆, Tamil: சிங்கப்பூர் தேசிய காப்பகம்) is the national archives of Singapore. It was formed in August 1993 with the merging of the National Archives and the Oral History Department. The NAS is responsible for the collection and management of records relating to the nation's political, social and economic history. NAS also identifies and collects records of historical significance from local and overseas private sources. In 1993, both NAS and the National Museum of Singapore were brought under the administration of the National Heritage Board. Since 1 November 2012, the NAS was brought under the administration of the National Library Board (NLB). The National Archives was originally established in 1968 for the preservation and administration of the nation's archives. It holds records as far back as 1800, 19 years before the ...

Lee Kong Chian Natural History Museum
The Lee Kong Chian Natural History Museum (LKCNHM) (Chinese: 李光前自然历史博物馆) is a museum of natural history at the Kent Ridge Campus of the National University of Singapore. It is named after Lee Kong Chian, a prominent Chinese businessman and philanthropist active in Malaya and Singapore between the 1930s and the 1960s. It was officially opened on 18 April 2015. The idea for a natural history collection was first mooted by Sir Stamford Raffles, and the collection of Southeast Asian biodiversity was begun in 1849 at the Raffles Museum (now the National Museum of Singapore). In 1972, the Government of Singapore removed the natural history collections from the National Museum and gave them to the Zoology Department of what was then the University of Singapore. They were housed in various temporary premises, including the Nanyang Technological University for seven years. Subsequently, they were returned to the NUS and housed in the Raffles Museum of Biodiversity Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oviposition
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word '' scāpus'', meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the ...

Sexually Dimorphic
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated d ...

Synthorax
The thorax is the midsection ( tagma) of the hexapod body (insects and entognathans). It holds the head, legs, wings and abdomen. It is also called mesosoma or cephalothorax in other arthropods. It is formed by the prothorax, mesothorax and metathorax and comprises the scutellum; the cervix, a membrane that separates the head from the thorax; and the pleuron, a lateral sclerite of the thorax. In dragonflies and damselflies the mesothorax and metathorax are fused together to form the synthorax. In some insect pupae, like the mosquitoes', the head and thorax can be fused in a cephalothorax. Members of suborder Apocrita (wasps, ants and bees) in the order Hymenoptera have the first segment of the abdomen fused with the thorax, which is called the propodeum. The head is connected to the thorax by the occipital foramen, enabling a wide range of motion for the head. In most flying insects, the thorax allows for the use of asynchronous muscles Asynchronous muscles are muscle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...
