Synthemistidae
The Synthemistidae are the family of dragonflies commonly known as tigertails, or sometimes called southern emeralds. This family is sometimes treated as a subfamily of Corduliidae. This is an ancient dragonfly family, with some species occurring in Australia and New Guinea. Most species are small in size and have narrow abdomens. Their nymphs are bottom dwellers, and resist droughts by burying themselves very deeply. Synthemistid dragonflies frequently prefer marshy areas, as well as fast-flowing streams. The family Synthemistidae is sometimes called Synthemidae. Genera The family Synthemistidae includes the following genera: * ''Apocordulia'' * '' Archaeophya'' * '' Archaeosynthemis'' * ''Austrocordulia'' * ''Austrophya'' * '' Austrosynthemis'' * '' Choristhemis'' * ''Cordulephya'' * '' Eusynthemis'' * '' Gomphomacromia'' * ''Hesperocordulia'' * '' Idionyx'' * '' Idomacromia'' * ''Lathrocordulia'' * '' Lauromacromia'' * '' Macromidia'' * ''Micromidia'' * '' ...

Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

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] |
Insect
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] |
Odonata
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 ... [...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 ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

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 ...
