Euphaeidae
Euphaeidae, sometimes incorrectly named Epallagidae and commonly called gossamerwings, is a family of damselflies in the odonate superfamily Calopterygoidea. The family is small, consisting of around 78 species living species in nine genera occurring in the Palearctic, Australasia, and Asia. The family contains two subfamilies, Euphaeinae, encompassing all the living species and a single fossil genus, and the extinct Eodichromatinae, encompassing fossil genera from the Eocene to late Oligocene. Euphaeid species are large and mostly metallic-coloured, looking similar to species of damselflies in the family Calopterygidae. The larvae have seven pairs of supplementary gills along the abdomen in addition to the usual three sac-like gills at the tip of the abdomen. Adults have the fore- and hindwings of equal length, barely petiolate and a long pterostigma that is broader in the hindwing. Adults have close veins and numerous antenodals (15-38), and most breed in forest streams. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Republica (damselfly)
''Republica'' is an extinct zygopteran genus in the damselfly family Euphaeidae with a single described species, ''Republica weatbrooki''. The species is solely known from the Early Eocene sediments exposed in the northeast of the U.S. state of Washington. Distribution ''Republica weatbrooki'' is known from a single location in the Eocene Okanagan Highlands, an outcrop of the Ypresian Klondike Mountain Formation in Republic. The holotype was recovered from the UWBM site B4131, which is designated the type locality, on May 24, 2006. Modern work on the fossil-bearing strata of the formation via radiometrically dating has given an estimated age in the Late Ypresian stage of the early Eocene, between at the youngest, with an oldest age estimate of , given based on detrital zircon isotopic data published in 2021. History and classification ''Republica weatbrooki'' was identified from only the type specimen, the holotype, number SR 06-59-08, which is a compression fossil preser ...

Cryptophaea (damselfly)
''Cryptophaea'' is a small genus of damselflies in the family Euphaeidae. Taxonomy The genus was circumscribed by the Finnish entomologist Matti Hämäläinen in 2003 to accommodate several species of damselflies in the family Euphaeidae that were previously misclassified or newly discovered. The genus was created based on specimens from Thailand that were initially misidentified as ''Schmidtiphaea schmidi'' Asahina, 1978. The type species of the genus is ''Cryptophaea saukra'', described from specimens collected in Doi Suthep, Chiang Mai province, Thailand. ''Cryptophaea'' is distinct from '' Bayadera'', which has a shorter abdomen, shorter wing petiolation, and only one crossvein in the cubital space. It also differs from '' Schmidtiphaea'', which has fore and hind wings of equal length and the pterostigma of the hind wing broader and placed more apically. Description ''Cryptophaea'' damselflies are characterised by their small and slender thorax, narrow clear wings, and lo ... [...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, 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 fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euphaea Fraseri
''Euphaea fraseri'', Malabar torrent dart, is a species of damselfly in the family Euphaeidae. This species is endemic to the Western Ghats; known to occur in various locations up to Goa. Description and habitat It is a medium-sized damselfly with black head and brown-capped pale grey eyes. Its thorax is black, marked with sky-blue antehumeral and reddish-yellow humeral stripes. Lateral sides of the thorax in the base is red. Legs are red as in '' Euphaea cardinalis''; but first pair is dark. Wings are narrower than '' Euphaea cardinalis''; hind-wings are shorter than fore-wings. Fore-wings are transparent, merely infused with brown on the apices. Hind-wings are transparent; but one third of the wings from the apices are broadly black. Abdomen is bright red up to the segment 7; apical third of segment 7 to the end segment are black. Anal appendages are black. Female is short and robust; the ochreous-red of male is replaced with yellow colors. All wings are transparent, infused ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Aix-en-Provence Formation
Aix-en-Provence, or simply Aix, is a city and commune in southern France, about north of Marseille. A former capital of Provence, it is the subprefecture of the arrondissement of Aix-en-Provence, in the department of Bouches-du-Rhône, in the region of Provence-Alpes-Côte d'Azur. The population of Aix-en-Provence is approximately 145,000. Its inhabitants are called ''Aixois'' or, less commonly, ''Aquisextains''. History Aix (''Aquae Sextiae'') was founded in 123 BC by the Roman consul Sextius Calvinus, who gave his name to its springs, following the destruction of the nearby Gallic oppidum at Entremont. In 102 BC its vicinity was the scene of the Battle of Aquae Sextiae, where the Romans under Gaius Marius defeated the Ambrones and Teutones, with mass suicides among the captured women, which passed into Roman legends of Germanic heroism. In the 4th century AD it became the metropolis of Narbonensis Secunda. It was occupied by the Visigoths in 477. In the succeeding c ...
