Argiinae is a subfamily of damselflies in the family Coenagrionidae, the pond damselflies. It contains the genus Argia.
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.
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies 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 beginning about 299 million years ago, and are found on every continent except Antarctica.
Enallagma cyathigerum is a species found mainly between latitudes 40°N and 72°N; It is widely distributed in the Palearctic, and the Nearctic species Enallagma annexum was at one time considered to be synonymous with it. The species can reach a length of 32 to 35 mm. It is common in many different countries including Russia, Sweden, Norway, Finland, the United States of America, and South Korea. Damselflies are an important link between the health of the aquatic ecosystem and its response to climate change.
The large red damselfly is a species of damselflies belonging to the family Coenagrionidae. It is native to the western Palearctic.
The blue-tailed damselfly or common bluetail is a damselfly, belonging to the family Coenagrionidae.
The azure damselfly is a species of damselfly found in most of Europe. It is notable for its distinctive black and blue colouring. They are commonly found around ponds and lakesides during the summer.
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.
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, 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 Lestidae are a rather small family of cosmopolitan, large-sized, slender damselflies, known commonly as the spreadwings or spread-winged damselflies.
The dainty damselfly, also known as the dainty bluet, is a blue damselfly of the family Coenagrionidae. This is a scarce species found mainly in southern Europe, northern Africa, southwest Asia, and Central America. C. scitulum are Odonata predators that can reach a length of 30–33 mm at maturity and have hind-wing lengths of 15–20 mm. The males and females do exhibit differing features through their colouration making them easily distinguishable. As shown in the photo to the left, segment eight is blue in colour followed by black markings on segment nine, whereas the females are mostly black near the rear with smaller blue markings. Although they are relatively simple to sex, they are easily confused with the common blue damselfly.
The River Glaven in the eastern English county of Norfolk is 10.5 mi (16.9 km) long and flows through picturesque North Norfolk countryside to the North Sea. Rising from a tiny headwater in Bodham the river starts 2+1⁄2 miles before Selbrigg Pond where three small streams combine. The scenic value of the Glaven valley is important to the tourist industry in North Norfolk. The river is one of over 200 chalk rivers in the world and one of 160 in the UK.
The Platycnemididae are a family of damselflies. They are known commonly as white-legged damselflies. There are over 400 species native to the Old World. The family is divided into several subfamilies.
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.
Chlorocyphidae is a family of damselflies, commonly known as jewels. These are colorful species native to the Old World tropics, where they occur along forest streams. They are most diverse in Southeast Asia.
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.
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.
Cyanocnemis is a monotypic genus of damselflies in the family Platycnemididae containing the single species Cyanocnemis aureofrons. This species is endemic to Indonesia, where it is known only from the 1939 type collections made in what is now the province of Papua on the island of New Guinea.
Idiocnemis is a genus of damselflies in the family Platycnemididae. They are distributed on New Guinea and the surrounding islands. There are 20 species.
Umma gumma is a species of damselfly in the family Calopterygidae. The genus name was established in 1890 and this species described in 2015 from Africa was found to belong to the genus. The species was named after the Pink Floyd album Ummagumma.
