Libellula Angelina
''Libellula angelina'', also known as bekko tombo, is a species of dragonfly in the family Libellulidae, native to China and Japan. It is under threat by rapid loss of the ponds and other small water bodies it uses as habitat, and is currently classified as critically endangered by the IUCN. Description The bekko tombo is a golden to rusty-brown dragonfly, with a dark stripe down the centre of the abdomen and a distinctive pattern of dark markings on its wings. Like other members of the family Libellulidae, this dragonfly has a relatively short, broad abdomen, and its body is distinctly shorter than its wingspan. Distribution and habitat The bekko tombo occurs in central and northern China, Japan (Honshu, Shikoku, Kyushu and offshore islands) and Korea. It inhabits old and stable ponds with moderate plant growth in lowland hill areas. It requires clear, open water in which the nymphs crawl around in the bottom sediments. Ecology The bekko tombo is univoltine. It has a larval pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edmond De Sélys Longchamps
Baron Michel Edmond de Selys Longchamps (25 May 1813 – 11 December 1900) was a Belgian Liberal Party politician and scientist. Selys Longchamps has been regarded as the founding figure of odonatology, the study of the dragonflies and damselflies. His wealth and influence enabled him to amass one of the finest collections of neuropteroid insects and to describe many species from around the world. His collection is housed in the Royal Belgian Institute of Natural Sciences. Biography Selys was a wealthy aristocrat born in Paris to Michel Laurent de Selys Longchamps and Marie-Denise Gandolphe. He was educated at home by private tutors and never attended school or university. Nevertheless, he became known as the world's leading authority on Odonata as well as an expert on Neuroptera and European Orthoptera. He was also a leading ornithologist. A Liberal Party representative in the Belgian Parliament, he became Councillor for Waremme in 1846, entered the Belgian Senate in 1855, a ...

Insects Of Korea
Insects (from Latin ') are pancrustacea Pancrustacea is the clade that comprises all crustaceans and hexapods. This grouping is contrary to the Atelocerata hypothesis, in which Myriapoda and Hexapoda are sister taxa, and Crustacea are only more distantly related. As of 2010, the Pan ...n Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes and one pair of antenna (biology), 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.

Odonata Of Asia
Odonata is an order of flying insects that includes the dragonflies and damselflies. Members of the group first appeared during the Triassic, though members of their total group, Odonatoptera, first appeared in Late Carboniferous. The two common groups are distinguished with dragonflies, placed in the suborder Epiprocta, usually being larger, with eyes together and wings up or out at rest, while damselflies, suborder Zygoptera, are usually smaller with eyes placed apart and wings along body at rest. All Odonata have aquatic larvae called naiads (nymphs), and all of them, larvae and adults, are carnivorous. The adults can land, but rarely walk. Their legs are specialised for catching prey. They are almost entirely insectivorous. Etymology and terminology Fabricius coined the term ''Odonata'' in 1793 from the Ancient Greek ( Ionic form of ) 'tooth'. One hypothesis is that it was because their maxillae are notably toothed. Most insects also have toothed mandibles. The wor ...

Largemouth Bass
The largemouth bass (''Micropterus salmoides'') is a carnivorous freshwater gamefish in the Centrarchidae ( sunfish) family, a species of black bass native to the eastern and central United States, southeastern Canada and northern Mexico, but widely introduced elsewhere. It is known by a variety of regional names, such as the widemouth bass, bigmouth bass, black bass, bucketmouth, largies, Potter's fish, Florida bass, Florida largemouth, green bass, bucketmouth bass, Green trout, gilsdorf bass, Oswego bass, LMB, and southern largemouth and northern largemouth. The largemouth bass is the state fish of Georgia and Mississippi, and the state freshwater fish of Florida and Alabama. Taxonomy The largemouth bass was first formally described as ''Labrus salmoides'' in 1802 by the French naturalist Bernard Germain de Lacépède with the type locality given as the Carolinas. Lacépède based his description on an illustration of a specimen collected by Louis Bosc near Charleston, S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Univoltine
Voltinism is a term used in biology to indicate the number of broods or generations of an organism in a year. The term is most often applied to insects, and is particularly in use in sericulture, where silkworm varieties vary in their voltinism. * Univoltine (monovoltine) – (adjective) referring to organisms having one brood or generation per year * Bivoltine (divoltine) – (adjective) referring to organisms having two broods or generations per year *Trivoltine – (adjective) referring to organisms having three broods or generations per year * Multivoltine (polyvoltine) – (adjective) referring to organisms having more than two broods or generations per year * Semivoltine – There are two meanings: :* (''biology'') Less than univoltine; having a brood or generation less often than once per year :* or (adjective) referring to organisms whose generation time is more than one year. Examples The speckled wood butterfly is univoltine in the northern part of its range, e.g. north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nymphs
A nymph ( grc, νύμφη, nýmphē, el, script=Latn, nímfi, label=Modern Greek; , ) in ancient Greek folklore is a minor female nature deity. Different from Greek goddesses, nymphs are generally regarded as personifications of nature, are typically tied to a specific place or landform, and are usually depicted as maidens. They were not necessarily immortal, but lived much longer than human beings. They are often divided into various broad subgroups, such as the Meliae (ash tree nymphs), the Dryads (oak tree nymphs), the Naiads (freshwater nymphs), the Nereids (sea nymphs), and the Oreads (mountain nymphs). Nymphs are often featured in classic works of art, literature, mythology, and fiction. Since the Middle Ages, nymphs have been sometimes popularly associated or even confused with fairies. Etymology The Greek word has the primary meaning of "young woman; bride, young wife" but is not usually associated with deities in particular. Yet the etymology of the noun remains u ...

Korea
Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic of Korea) comprising its southern half. Korea consists of the Korean Peninsula, Jeju Island, and several minor islands near the peninsula. The peninsula is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the Sea of Japan (East Sea). During the first half of the 1st millennium, Korea was divided between three states, Goguryeo, Baekje, and Silla, together known as the Three Kingdoms of Korea. In the second half of the 1st millennium, Silla defeated and conquered Baekje and Goguryeo, leading to the "Unified Silla" period. Meanwhile, Balhae formed in the north, superseding former Goguryeo. Unified Silla eventually collapsed into three separate states due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dragonfly
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of true dragonfly are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterized 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 colouration, 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, along or ...
