Acanthacorydalis Fruhstorferi
''Acanthacorydalis fruhstorferi'' is a species of dobsonfly native to Vietnam and China. It holds the title of largest aquatic insect by wingspan according to the Guinness Book of World Records at 21.6 cm. The title formerly belonged to the Brazilian damselfly '' Microstigma rotundatum''. ''Acanthacorydalis fruhstorferi'' was first described by Herman Willem van der Weele in 1907 from a specimen from "Than-Moi" (probably in Lạng Sơn Province), Vietnam. It is found throughout Southern China (Fujian, Guangxi, Guangdong, Guizhou, Jiangxi, Yunnan, and Zhejiang) and Northern Vietnam. Liu and associates proposed in 2005 that the species is most closely related to '' Acanthacorydalis sinesis'' citing morphological similarities relative to similar Chinese genera of '' Acanthacorydalis''. Specifically the wing and body colouration, yet differed by ''A.sinesiss lack of sagittal dorsal division. Life history Eggs are deposited between stones near flowing water. Larvae inhabit strea ...

Insects Of China
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corydalidae
The family Corydalidae contains the megalopterous insects known as dobsonflies and fishflies. Making up about one dozen genera,See references in Haaramo (2008) they occur primarily throughout the Northern Hemisphere, both temperate and tropical, and South America. They are sizeable Megaloptera, with a body usually larger than 25 mm (1 inch). They often have long filamentous antennae, though in male fishflies they are characteristically feathered. Ocelli are present; the fourth tarsal segment is cylinder-shaped. The four large wings are translucent, smoky grey, or mixed, and the anterior pair is slightly longer than the posterior one. Their aquatic larvae are used as fish bait and are called hellgrammites. The eastern dobsonfly, ''Corydalus cornutus'', is the most well-known North American species among the dobsonflies. These genera have distinctive elongated mandibles in males and form the subfamily Corydalinae. The genera in which the males have normal mandibles, called ...

List Of Largest Insects
Insects, which are a type of arthropod, are the most numerous group of multicellular organisms on the planet, with over a million species identified so far. The title of heaviest insect in the world has many contenders, the most frequently crowned of which is the larval stage of the goliath beetle, '' Goliathus goliatus'', the maximum size of which is at least and . The highest confirmed weight of an adult insect is for a giant weta, ''Deinacrida heteracantha'', although it is likely one of the elephant beetles, '' Megasoma elephas'' and ''Megasoma actaeon'', or goliath beetles, both of which can commonly exceed and , can reach a greater weight. The longest insects are the stick insects, see below. Representatives of the extinct dragonfly-like order Meganisoptera (also known as griffinflies) such as the Carboniferous ''Meganeura monyi'' and the Permian ''Meganeuropsis permiana'' are the largest insect species ever known. These creatures had a wingspan of some . Their maxim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hans Fruhstorfer
Hans Fruhstorfer (7 March 1866, in Passau, Germany – 9 April 1922, in Munich) was a German explorer, insect trader and entomologist who specialised in Lepidoptera. He collected and described new species of exotic butterflies, especially in Adalbert Seitz's ''Macrolepidoptera of the World''. He is best known for his work on the butterflies of Java. His career began in 1888 when he spent two years in Brazil. His expedition in Brazil was financially successful and led to his becoming a professional collector. After his successful endeavor, he spent some time in Sri Lanka (then Ceylon), then in 1890 he went to Java for three years, visiting Sumatra. Between 1895 and 1896 he collected in Sulawesi, Lombok and Bali. In 1899, he went on a three-year journey to the United States, Oceania, Japan, China, Tonkin, Annam and Siam, returning via India. Following his travels, he settled in Geneva where he wrote monographs based on the specimens in his extensive private collection. Many of th ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Corydalus
''Corydalus'' is a genus of large flying insects in the Corydalidae family, commonly known as dobsonflies. They are endemic to North, Central and South America and there are about 35 known species. Members of the genus have wing lengths of up to 85 millimetres. They are sexually dimorphic, with the males having large mandibles used to grasp the females during mating while the females have smaller jaws. The larvae are known as hellgrammites and are aquatic predators. Etymology ''Corydalus'' (also transcribed corydalis) comes from the Greek (κορυδαλλις) meaning a crested lark or the flower, larkspur, apparently related to Greek corys (κορυς) a helmet crest. The name probably refers to the long mandibles of the male which might be considered to resemble the crest of a lark, or perhaps, the decorative crests of a helmet.

Helmet
A helmet is a form of protective gear worn to protect the head. More specifically, a helmet complements the skull in protecting the human brain. Ceremonial or symbolic helmets (e.g., a policeman's helmet in the United Kingdom) without protective function are sometimes worn. Soldiers wear combat helmets, often made from Kevlar or other lightweight synthetic fibers. The word ''helmet'' is derived from ''helm'', an Old English word for a protective head covering. Helmets are used for recreational activities and sports (e.g., jockeys in horse racing, American football, ice hockey, cricket, baseball, camogie, hurling and rock climbing); dangerous work activities such as construction, mining, riot police, military aviation, and in transportation (e.g. motorcycle helmets and bicycle helmets). Since the 1990s, most helmets are made from resin or plastic, which may be reinforced with fibers such as aramids. Designs Some British gamekeepers during the 18th and 19th centuries wore he ...

Acantha
Acantha (Ancient Greek: , English translation: "thorn") is often claimed to be a minor character in Greek mythology whose metamorphosis was the origin of the '' Acanthus'' plant.Coulter, Charles Russell and Turner, Patricia (2000).

Mythology The tale supposedly goes that Acantha was a nymph loved by the god Apollo. Acantha, however, rebuffed Apollo's advances and scratched his face. As a result, Apollo transformed her into the Acanthus, a plant with spiny leaves. Beeton, Samuel Orchart (1871). ''Beeton's Classical dictionary''. Warwick. pg.2.

Phototaxis
Phototaxis is a kind of taxis, or locomotory movement, that occurs when a whole organism moves towards or away from a stimulus of light. This is advantageous for phototrophic organisms as they can orient themselves most efficiently to receive light for photosynthesis. Phototaxis is called positive if the movement is in the direction of increasing light intensity and negative if the direction is opposite. Two types of positive phototaxis are observed in prokaryotes. The first is called scotophobotaxis (from the word " scotophobia"), which is observed only under a microscope. This occurs when a bacterium swims by chance out of the area illuminated by the microscope. Entering darkness signals the cell to reverse flagella rotation direction and reenter the light. The second type of phototaxis is true phototaxis, which is a directed movement up a gradient to an increasing amount of light. This is analogous to positive chemotaxis except that the attractant is light rather than a chem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
