Damselflies
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 ...

Dragonflies
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 ...

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] |

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.

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] |
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] |
Isostictidae
Isostictidae is a small family of medium-sized to large damselflies restricted to Australia, New Caledonia, and New Guinea. It contains 12 genera and more than 40 species. Members of this family resemble species in the threadtail family (Protoneuridae). Diagnosis *Adult: The adults are small to medium in size with a length of 15–40 mm. They have two antenodal crossveins, most postnodal crossveins aligned with crossveins behind them, quadrilateral cell almost rectangular, no supplementary intercalary longitudinal veins, and an anal vein fused with wing margin. Their antennae are seven-segmented. *Larva: The larva has a labial mask short, flat, palps narrow, palpal setae present, premental setae variable, median lobe shallowly cleft; caudal gills saccular to triquetral, strongly nodate.

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.
