''Chalcolestes'' is a small genus of damselfly in the family Lestidae. They are commonly known as Willow Spreadwings. They are similar to the Spreadwings of the genus Lestes ''Lestes'' is a genus of damselfly in the family Lestidae. The family hold their wings at about 45 degrees to the body when resting.

Chalcolestes Viridis
''Chalcolestes viridis'', formerly ''Lestes viridis'', is a damselfly of the family Lestidae. It has a metallic green body and at rest it holds its wings away from its body. Its common name is the willow emerald damselfly, the green emerald damselfly, or the western willow spreadwing. It has an elongated abdomen and pale brown spots on its wings and resides in areas of still water with overhanging trees. Taxonomy The genus ''Chalcolestes'' is separated from ''Lestes'' because of differences in their larvae. A closely related species '' C. parvidens'' used to be considered a sub-species of ''C. viridis''. ''C. parvidens'' occurs in Greece, Bulgaria, Croatia and in Italy; near Rome it flies with ''C. viridis'' in the same ponds. There are small morphological differences between the two species both as adults and larvae and analysis of proteins from the two species, by electrophoresis, also supports their separation into two species, but they are hard to tell apart in the field. ...

Chalcolestes Parvidens
''Chalcolestes parvidens'', formerly ''Lestes parvidens'', is a damselfly of the family Lestidae. It has a metallic green body and at rest it holds its wings away from its body. Its common name in English is the eastern willow spreadwing. Taxonomy The genus ''Chalcolestes'' is separated from ''Lestes'' because of differences in their larvae. ''C. parvidens'' is closely related to '' C. viridis'' and used to be considered a subspecies of ''C. viridis'', however there are small morphological differences between the two species both as adults and larvae and analysis of proteins from the two species, by electrophoresis Electrophoresis, from Ancient Greek ἤλεκτρον (ḗlektron, "amber") and φόρησις (phórēsis, "the act of bearing"), is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric fie ..., also supports their separation into two species, but they are hard to tell apart in the field.

Lestidae
The Lestidae are a rather small family of cosmopolitan, large-sized, slender damselflies, known commonly as the spreadwings or spread-winged damselflies. Characteristics While most damselflies rest with their wings folded together, most members of the family Lestidae hold them at an angle away from their bodies. The pterostigma (a single dark spot in the meshwork of the leading edge near the tip of each wing) is noticeably elongated. The quadrilateral (a part of the wing venation, close to the body) has an acute angle at the end. The body has a greenish, metallic shine. The superior anal appendages, commonly called claspers (body parts of male insect for clasping the female during copulation) of male spreadwings are long and strongly curved. Breeding takes place in slow-moving or still water in stream backwaters, swamps, marshes and temporary pools. The nymphs have a long abdomen and a distinctive prementum (part of the lower lip). There is one generation per year in North Ame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Damselfly
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are 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. An ancient group, damselflies have existed since at least the Lower Permian, 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 the ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 taxonomy (biology), 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 ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...
