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 Goliathus, goliath beetle, ''Goliathus goliatus'', the maximum size of which is at least and . The highest confirmed weight of an adult insect is for a gravid female giant weta, ''Deinacrida heteracantha'', although it is likely that one of the elephant beetles, ''Megasoma elephas'' and ''Megasoma actaeon'', or Goliathus, 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 (biology), order Meganisoptera (also known as griffinflies) such as the Carboniferous ''Meganeura monyi'' and the Permian ''Meganeuropsis permiana'' are the largest insect species ever known. ...

Meganeura Monyi
''Meganeura'' is a genus of extinct insects from the Late Carboniferous (approximately 300 million years ago). It is a member of the extinct order Meganisoptera, which are closely related to and resemble dragonflies and damselflies (with dragonflies, damselflies and meganisopterans being part of the broader group Odonatoptera). Like other odonatopterans, they were predatory, with their diet mainly consisting of other insects. The genus belongs to the Meganeuridae, a family including other similarly giant dragonfly-like insects ranging from the Late Carboniferous to Middle Permian. With single wing length reaching and a wingspan about , ''M. monyi'' is one of the largest-known flying insect species. Fossils of ''Meganeura'' were first discovered in Late Carboniferous ( Stephanian) Coal Measures of Commentry, France in 1880. In 1885, French paleontologist Charles Brongniart described and named the fossil "''Meganeura''" (great-nerved), which refers to the network of veins on ...

Anax Strenuus
The giant Hawaiian darner (''Anax strenuus''), also known as the giant Hawaiian dragonfly or pinao, is a species of dragonfly in the family Aeshnidae. It is one of two species of dragonfly that is endemic to the Hawaiian Islands (the other is '' Nesogonia blackburni''). It is found near streams and wetlands on all islands of the archipelago and it has a wide altitude range, but is particularly common at higher elevations. This species is one the world's largest living dragonflies and the largest in the United States. It typically has a wingspan of , but has been verified to reach up to ; reports of considerably greater sizes are unverified and highly questionable. The only other member of the genus ''Anax'' in Hawaii is the closely related green darner (''A. junius''), but it is considerably smaller, mainly found in lowlands in Hawaii, and also found in Asia and North America.

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 Odonata, Odonates by wingspan, second only to ''Megaloprepus caerulatus'' (Pseudostigmatidae). ''T. plagiata'' is additionally the largest living dragonfly, with a maximum wingspan of , exceeding the wingspan of runner-up ''Petalura ingentissima'' at . 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 (biology), type locality was listed as Borneo.

Petalura Ingentissima
''Petalura ingentissima'', the giant petaltail, has been described as the world's largest dragonfly, with a wingspan of 160 mm. It is found in Queensland, Australia. Dr R.J. Tillyard described the giant petaltail in 1908. Its species name is derived from the Latin adjective ''ingens'' "huge". It is one of five species in the Australian genus ''Petalura''. A large heavily built dragonfly, the giant petaltail has a black body with some yellow markings. The female's wingspan can be 158–162 mm and body length 125 mm, the largest dragonfly species in overall dimensions although members of the genus ''Tetracanthagyna'' can have longer wings and ''Chlorogomphus, Chlorogomphus papilio'' a larger wing area. Measuring 5.9-6.3 cm long, the larvae are unusual in that they live in burrows along the river margin and hunt passing prey.

Megaloprepus Caerulatus
''Megaloprepus caerulatus'', also known as the blue-winged helicopter, is a forest giant damselfly of the family Coenagrionidae. Forest giant damselflies were previously recognized as their own family, Pseudostigmatidae. ''M. caerulatus'' is found in wet and moist forests in Central and South America. It has the greatest wingspan of any living damselfly or dragonfly, up to in the largest males. Its large size and the markings on its wings make it a conspicuous species; a hovering ''Megaloprepus'' has been described as a "pulsating blue-and-white beacon". As an adult it feeds on orb-weaver spiders in the forest understory, which it plucks from their webs. It lays its eggs in water-filled holes in trees; males defend the larger holes as breeding territories. The naiad is a top predator in its tree-hole habitat, feeding on tadpoles and aquatic insects, including the larvae of mosquito species that are vectors of human disease. Egg and naiad ''Megaloprepus'' lays its eggs in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Damselflies
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies (which constitute the other odonatan suborder, Epiprocta) but are usually smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. Damselflies have existed since the Late Jurassic, and are found on every continent except Antarctica. All damselflies are predatory insects: both nymphs and adults actively hunt and eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acidic bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, but their dependence on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dragonflies
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of dragonflies are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterised by a pair of large, multifaceted, compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural coloration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder ( Zygoptera) and are similar in body plan, though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, alo ...

Odonate
Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the '' Epiophlebia'' damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and wings folded together along body at rest. Adult odonates can land and perch, but rarely walk. All odonates have aquatic larvae called naiads or nymphs, and all of them, larvae and adults, are carnivorous and are almost entirely insectivorous, although at the larval stage they will eat anything that they can overpower, including small fish, tadpoles, and even adult newts. The adults are superb aerial hunters and their legs are specialised for catching prey in flight. Odonata in its narrow sense forms a subgroup of the broader Odonatoptera, which contains other dragonfly-like insects. T ...
