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 ...

Coenagrionidae
The insect family Coenagrionidae is placed 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 have a black pattern * Ground c ...

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 wo ...

Calopteryx Virgo
The beautiful demoiselle (''Calopteryx virgo'') is a European damselfly belonging to the family Calopterygidae. It is often found along fast-flowing waters where it is most at home. Subspecies Subspecies include: *''Calopteryx virgo britannica'' Conci, 1952 *''Calopteryx virgo festiva'' ( Brullé, 1832) (eastern Mediterranean) *''Calopteryx virgo meridionalis'' 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''. Mounted specimen Description Eggs and larvae Females lay up to 300 eggs at a time on emergent or floating plants, often on water-crowfoot. Like the banded demoiselle, they often submerge to do so. The eggs hatch after around 14 days. Again, like the banded demoiselle, the larva is stick-like with long legs and dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calopterygidae
The Calopterygidae are a family of 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. (2005)Evolution and ecology of Calopterygidae (Zygoptera: Odonata): status of knowledge and research perspectives.''Neotrop. Entomol'' 34(6), 861-879.

Flying Insect
The Pterygota ( grc, πτερυγωτός, pterugōtós, winged) are a subclass of insects that includes the winged insects. It also includes insect orders that are secondarily wingless (that is, insect groups whose ancestors once had wings but that have lost them as a result of subsequent evolution). The pterygotan group comprises almost all insects. The insect orders not included are the Archaeognatha (jumping bristletails) and the Zygentoma ( silverfishes and firebrats), two primitively wingless insect orders. Also not included is Entognatha, which consist of three orders no longer considered to be insects: Protura, Collembola, and Diplura. Systematics Traditionally, this group was divided into the infraclasses Paleoptera and Neoptera. The former are nowadays strongly suspected of being paraphyletic, and better treatments (such as dividing or dissolving the group) are presently being discussed. In addition, it is not clear how exactly the neopterans are related among eac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 of Myanmar.

Perilestidae
The Perilestidae are a family of damselflies commonly known as shortwings and twigtails.Haber, W. and Wagner, DPerilestidae: Shortwings.Dragonflies and Damselflies of Ecuador. It is a small family of around 19 species.Neiss, U. G. and Neusa, H. (2010)The larva of ''Perilestes attenuatus'' Selys, 1886 (Odonata: Perilestidae) from Amazonas, Brazil.''Zootaxa'' 2614 53-58. All extant species are native to the Neotropical realm. In the past ''Nubiolestes'' of Africa was included in this family, but this is doubted. ''Palaeoperilestes electronicus'' is an extinct species described from mid-Cretaceous Burmese amber. These damselflies are short-winged and have very long, slender, color-banded abdomens. They live in dense forest habitat and rest with their abdomens hanging vertically.Machado, A. (2015)''Perilestes eustaquioi'' sp. nov. and new distributional records of Perilestidae (Odonata) in Brazil.''Zoologia (Curitiba)'', 32(5), 428-430.

Pseudostigmatidae
The Pseudostigmatidae are a family of tropical damselflies, known as helicopter damselflies, giant damselflies, or forest giants. The family includes the largest of all damselfly species. They specialize in preying on web-building spiders, and breed in phytotelmata, the small bodies of water held by plants such as bromeliads. Range The species traditionally placed in Pseudostigmatidae are all Neotropical. Two range as far as northeastern Mexico: ''Mecistogaster ornata'' occurs in Tamaulipas and ''Pseudostigma aberrans'' in both Tamaulipas and Nuevo León. In 2006, Molecular phylogeny, molecular phylogenetic analysis confirmed that the African damselfly ''Coryphagrion grandis'', previously often classified within Megapodagrionidae or in a monotypic family Coryphagrionidae, belonged within family Pseudostigmatidae, close to genus ''Mecistogaster'', as was proposed already ten years before. This finding suggests that the family dates back to before the breakup of the supercont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
