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] |
Calopterygidae
Calopterygidae is a Family (biology), family of damselfly, damselflies, in the suborder Zygoptera. They are commonly known as the broad-winged damselflies, demoiselles, or jewelwings. These rather large damselflies have wingspans of 50–80 mm (compared to about 44 mm in the common bluetail damselfly, ''Ischnura elegans''), are often metallic-coloured, and can be differentiated from other damselflies by the broader connection between the wings and the body, as opposed to the abrupt narrowing seen in other damselfly families. The family contains some 150 species. The Calopterygidae are found on every continent except Antarctica. They live along rivers and streams.Córdoba-Aguilar, A. & Cordero-Rivera, A.

Calopteryx Virgo
The beautiful demoiselle (''Calopteryx virgo'') is a species of damselfly belonging to the family Calopterygidae. It is found in Europe, North Africa, and Western Asia, and are often found nearby fast-flowing waters. Subspecies There are currently five known subspecies: *''Calopteryx virgo britannica'' Conci, 1952 *''Calopteryx virgo festiva'' (Gaspard Auguste Brullé, Brullé, 1832) (eastern Mediterranean) *''Calopteryx virgo meridionalis'' Edmond de Sélys Longchamps, Sélys, 1853 (western Mediterranean and south-west France) *''Calopteryx virgo padana'' Conci, 1956 (northern Italy) *''Calopteryx virgo virgo'' (Linnaeus, 1758) File: Calopteryx virgo meridionalis.jpg, ''Calopteryx virgo meridionalis'' File:Calopteryx virgo meridionalis MHNT.jpg, ''C. v. meridionalis''.

Coenagrionidae
Coenagrionidae is a family of damselflies, also known as pond damselflies, in the order Odonata and the suborder Zygoptera. The Zygoptera are the damselflies, which although less known than the dragonflies, are no less common. More than 1,300 species are in this family, making it the largest damselfly family. The family Coenagrionidae has six subfamilies: Agriocnemidinae, Argiinae, Coenagrioninae, Ischnurinae, Leptobasinae, and Pseudagrioninae. This family is referred to as the narrow-winged damselflies or the pond damselflies. The Coenagrionidae enjoy a worldwide distribution, and are among the most common of damselfly families. This family has the smallest of damselfly species. More than 110 genera of the family Coenagrionidae are currently accepted.Integrated Taxonomic Information System (2007)Coenagrionidae retrieved November 4, 2007. Etymology The name may be derived from Greek ''coen'' meaning shared or common and ''agrio'' meaning fields or wild. Characteristics * Usually ...

Odonata
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ischnura Heterosticta
''Ischnura heterosticta'', one of at least two species with the common name Common Bluetail (other), common bluetail, is an Australian damselfly of the family Coenagrionidae. It is the largest of the three ''Ischnura'' species in Australia. They are generally found near slow-running or still water. The species is also salt tolerant. It flies from October to March. Description The common bluetail is a small damselfly. Most males have blue eyes, a blue thorax, and a blue ringed tail. The females have a variety of forms including green, brown, black, and a form with very similar colourings to the male. Distribution In Australia, ''Ischnura heterosticta'' is found throughout the entire continent including Tasmania.

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] |

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 ...

Platystictidae
Platystictidae is a family of damselflies, commonly known as shadowdamsels. They look very similar to the threadtail damselfly family ( Protoneuridae). They can mostly be found throughout Asia, Central America, and South America. Most members of this family live in dense forests in the tropics where they are found around streams. Their wings are narrow and their abdomen slender and elongated. The adults probably do not disperse far as many species are known from a single location or have small ranges and there are probably other species as yet undescribed. The oldest members of the family belong to the genus '' Mesosticta'' from the Cenomanian aged Burmese amber Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar.
