Calopteryx dimidiata, the sparkling jewelwing, is a species of damselfly in the family Calopterygidae. It is endemic to the eastern and southeastern United States. Its natural habitat is woodland and open areas near forest rivers and streams.
The sparkling jewelwing is one of the smallest damselflies in its family with a total length of 37 to 50 millimetres (1.5 to 2.0 in). The thorax and the long slender abdomen are metallic bluish-green and the eyes are brown. In males the end fifth of each wing is black, with a straight line separating the dark section from the transparent hyaline remainder of the wing. Females are a slightly more bronzy-green. Their wings may be similar to those of the male but less clearly defined, or only the hind wings may be tipped with black, or the wings may be entirely clear. There is usually a small white pterostigma near the tip of the wings. Immature adults have reddish eyes and generally duller colouring. [3]
The male sparkling jewelwing has fore-wings and hind wings that do not differ in size by more than 2 millimetres (0.08 in). The apex of both pairs of wing has a black band that terminates in a straight line distal to the nodus. The sternum of the tenth abdominal segment is black. These features distinguish this species from the others in its genus that share its range. [2]
The sparkling jewelwing is found in the eastern and southeastern United States. Its range extends from New England to Louisiana and parts of Texas, mainly on the Atlantic coastal plain. Its typical habitat is sandy forest streams, particularly acidic ones, with fast-flowing water in locations with plentiful riverside vegetation. [3]
The sparkling jewelwing is on the wing between May and September in New Jersey but between February and November in Florida. Both males and females can often be seen together near breeding sites, with males patrolling small territories, circling and chasing off rivals. When a female is present, ritualised courtship flights precede copulation which lasts for about two minutes. After this, the female walks down the stem of an emergent plant and spends about fifteen minutes underwater, laying a batch of several hundred eggs before returning to the surface. [3]
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. Damselflies have existed since the Jurassic, and are found on every continent except Antarctica.
The banded demoiselle is a species of damselfly belonging to the family Calopterygidae. It is often found along slow-flowing streams and rivers. It is a Eurasian species occurring from the Atlantic coast eastwards to Lake Baikal and northwestern China.
The beautiful demoiselle is a species of damselfly belonging to the family Calopterygidae. It is found in Europe, North Africa, and Western Asia. It is often found along fast-flowing waters.
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.
Calopteryx angustipennis is a species of damselfly in the family Calopterygidae known commonly as the Appalachian jewelwing. It is endemic to the United States, where it occurs in the southeastern and eastern states.
Calopteryx is a genus of large damselflies belonging to the family Calopterygidae. The colourful males often have coloured wings whereas the more muted females usually have clear wings although some develop male (androchrome) wing characteristics. In both sexes, there is no pterostigma.
Calopteryx exul is an endangered species of damselfly in the family Calopterygidae. It is found in Algeria, Morocco, and Tunisia. The largest populations found were located in Northeast Algeria. Its natural habitat is along rivers that have fast flowing water, which are threatened by pollution.
Phaon iridipennis, commonly known as the glistening demoiselle or glinsterjuffertjie, is a species of damselfly in the family Calopterygidae.
The ebony jewelwing is a species of broad-winged damselfly. One of about 150 species of Calopterygidae, it is found in the eastern U.S. and southeastern Canada, ranging west to the Great Plains. Other common names include black-winged damselfly.
Calopteryx haemorrhoidalis is a species of damselfly in the family Calopterygidae known by the common names copper demoiselle and Mediterranean demoiselle.
The superb jewelwing is a species of damselfly in the family Calopterygidae. It is native to North America, where it is distributed in eastern Canada and the northeastern United States as far south as Tennessee.
The western demoiselle or yellow-tailed demoiselle is a species of damselfly belonging to the family Calopterygidae. It replaces the banded demoiselle in southern France and the Iberian Peninsula, and is sometimes considered a subspecies of that species.
Rhadinosticta simplex is a species of damselfly in the family Isostictidae. It is commonly known as the powdered wiretail. It is located in Australia, where it is fairly common and localised.
Vestalis gracilis, is a species of damselfly belonging to the family Calopterygidae. It is known commonly as the clear-winged forest glory or clear-winged flash-wing. It is native to Southeast Asia and surrounding regions.
Allocnemis leucosticta, the goldtail or goudstertjie, is a species of damselfly in the family Platycnemididae. It is endemic to South Africa and Eswatini, where it lives near streams and rivers in wooded areas.
The black stream glider, also known as the indigo dropwing is a species of dragonfly in the family Libellulidae. It is a very widespread species, occurring from Greece, Cyprus and Turkey, throughout Asia to New Guinea.
Proischnura polychromatica, the mauve bluet, is a small species of damselfly in the family Coenagrionidae. It is endemic to a small area of Cape Province in South Africa. The adult male has a mauve sheen to its dark-coloured body, a bronze-green thorax striped with mauve, and a pale brown abdomen with a bronze-green dorsal stripe. The female is mainly pale brown. The natural habitat of this damselfly is transient pools in stream beds with floating vegetation, especially sedges. Although previously more widespread, it is now known from a single location where it is threatened by the encroachment of cattle and the loss of suitable habitat. For these reasons, the International Union for Conservation of Nature has rated it as "endangered".
Calopteryx aequabilis, the river jewelwing, is a species of broad-winged damselfly. The species was first described by Thomas Say in 1839. It is one out of the 170 species of the Odonata found from northeastern Alberta to Newfoundland and south in most of the United States.
Neurobasis chinensis, stream glory is a species of damselfly in the family Calopterygidae. It is a common species distributed across much of Asia.
