Elattoneura glauca is a species of damselfly in the family Platycnemididae. It is known also as the common threadtail, the grey threadtail or gewone draadstertjie. It is native to the southern half of the African continent, where it is widespread. It lives in shady areas along rivers and streams. [1]
This is a smallish damselfly (wingspan of 40 mm (1.6 in)) which exhibits strong sexual dimorphism. Males have a pale blue thorax with a black lateral stripe. The long, slender abdomen is black, with a while underside, and a pale blue tip. There is a white ring at each joint. The eyes are turquoise. [3] [4]
Females and immature individuals are tan, with a narrow whitish band at each segment. Females have a whitish thorax with thick brown stripes. The eyes are pale and striped with brown bands. They are also larger than the males, with a more robust build. The mottled abdomen is less elongate. [3] [4] Females may easily be confused with Elattoneura frenulata in areas of range overlap. [5]
This species is widely distributed across the southern part of the African continent. It is locally common and may occur in large numbers in suitable habitat. [3] It can be found amongst bushes and grass along rivers and streams. It is usually found in shady areas near the water although individuals may be found further away, in thickets. They are mostly associated with slow flowing water. [5]
This species is sluggish and often reluctant to fly. [5] They are most common in summer, when they are frequently found perched on rocks or plant stems in pairs. [3] While they may persist year round at many sites, they are encountered far less frequently from late autumn through winter. [5]
Elattoneura, the African threadtails, is a genus of damselflies in the family Platycnemididae. They were formerly placed in genus Prodasineura, but form a distinct clade. The adults are smallish and delicately built damselflies, and their males have very wide heads. The adults are typically found in sheltered locations beside or over running water, though a few prefer calmer water with much detritus. There appears to be two groups with differing habitat preferences. Those with pruinose faces and mostly blue eyes occupy watercourses in open terrain, while those with black or brightly coloured faces are found along forested streams.
Phaon iridipennis, commonly known as the glistening demoiselle or glinsterjuffertjie, is a species of damselfly in the family Calopterygidae.
Prodasineura, the Asian threadtails, is a genus of damselflies in the family Protoneuridae. All the Afrotropical species formerly in this genus are now placed in Elattoneura, the African threadtails. Dijkstra et al. (2014) moved the genus from Protoneuridae to Platycnemididae based on molecular phylogenetic research.
Elattoneura frenulata is a species of damselfly in the family Platycnemididae known commonly as the sooty threadtail or Roetswartdraadstertjie. It is endemic to South Africa. It is a localised endemic of montane areas of the Western Cape, marginally expanding into the western parts of the Eastern Cape. Though it has a restricted distribution, it is locally common. It lives near slow-moving rivers with abundant vegetation.
The eastern billabongfly is a damselfly in the family Coenagrionidae. It is also known as the eastern dart. Eastern billabongflies are small damselflies about 25mm (1 inch) in length. They are found near slow running water or still water, such as lakes, ponds and ditches. Male and female eastern billabongflies mate in a wheel position.
Eastern forktail is a member of the damselfly family Coenagrionidae.
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.
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.
Pinheyschna subpupillata, the stream hawker, is a species of dragonfly in the family Aeshnidae.
Chlorolestes umbratus, the white malachite is a species of damselfly in the family Synlestidae. It is endemic to southern South Africa. This species is found along rivers and streams in both forest and fynbos.
Proischnura rotundipennis, the round-winged bluet is a species of damselfly in the family Coenagrionidae. It is endemic to South Africa, where it is scarce and localised.
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".
Ischnura erratica, the swift forktail, is a species of damselfly in the family Coenagrionidae. It is native to the Pacific Northwest, ranging from British Columbia to northern California.
Neoneura amelia, commonly known as Amelia's threadtail, is a species of damselfly in the family Protoneuridae. It is native to the southern United States and Central America, its range extending from the southern tip of Texas to Panama.
Nososticta solitaria is an Australian species of damselfly in the family Platycnemididae, commonly known as the fivespot threadtail. It is found only in north-eastern Australia.
Nososticta coelestina is an Australian species of damselfly in the family Platycnemididae, commonly known as the green-blue threadtail.
Acanthagrion quadratum, or Mexican wedgetail, is a pond damselfly of the family Coenagrionidae. It was first described by Edmond de Sélys Longchamps in 1876.
