Ischnura intermedia (Henri J. Dumont, 1974) | |
The Persian damselfly or Dumont's bluetail (Ischnura intermedia) is a damselfly, belonging to the family Coenagrionidae.
It was first described in Anatolia, Turkey in 1974 and has been reported from Syria, Iraq, Iran and Turkmenistan. It was discovered in Europe on the island of Cyprus in 2013 and has been recorded at 12 localities in the South West. [1] Globally it is classified as Near-threatened. It has not been evaluated for its conservation status in Europe, but is likely to be Endangered.
Permanent slow-flowing streams and channels with localized patches of reeds or other marshy vegetation [2]
Ischnura intermedia can reach a body length of 27–30 millimetres (1.1–1.2 in) and a wingspan of about 18 millimetres (0.71 in). Adult males are similar in size and appearance to I. elegans. Persian blue damselflies have a head and thorax patterned with blue and black. Both sexes have two-toned diamond-shaped pterostigma (wing spots) on the wings which are shorter than I. elegans. The wing spots are smaller on the hindwings. Eyes are blue. Males have a largely black abdomen with very narrow pale markings where each segment joins the next. Segment eight (S8) is entirely pale blue and S9, which is black on I. elegans, is also blue. There is a seasonal variation in the black and blue patterns on S8 and S9. Immature females in the aurantiaca phase have extensive orange colouration on the head, thorax, and the underside of the abdomen. On maturity, the orange colour changes to yellow or green.
I. intermedia is not an active flyer and adults typically rest 10–30 cm above the water. The flight season on Cyprus is from late March till mid-November.
Damselflies are 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.
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, Europe and South Korea. Damselflies are an important link between the health of the aquatic ecosystem and its response to climate change.

Ischnura senegalensis, also known variously as common bluetail, marsh bluetail, ubiquitous bluetail, African bluetail, and Senegal golden dartlet, is a widespread damselfly of the family Coenagrionidae. It is native from Africa, through the Middle East, to southern and eastern Asia.

Sympetrum danae, the black darter or black meadowhawk is a dragonfly found in northern Europe, Asia, and North America. At about 30 mm (1.2 in) long, it is Britain's smallest resident dragonfly. It is a very active late summer insect typical of heathland and moorland bog pools.
Ischnura aurora, golden dartlet, also known as the aurora bluetail, is a species of damselfly in the family Coenagrionidae.
Ischnura is a genus of damselflies known as blue tails in the family Coenagrionidae. Forktails are distributed worldwide, including various oceanic islands. The males have a forked projection at the tip of the abdomen which gives the group their common name.
The scarce blue-tailed damselfly or small bluetail is a member of the damselfly family Coenagrionidae.
The wildlife of Cyprus includes its flora and fauna and their natural habitats. Cyprus has a rich flora and a diverse fauna albeit with relatively few mammals. Like most modern countries, the natural habitats in Cyprus have been steadily disappearing, currently retaining only 20% of its original habitat due to rapid urbanization, usage of forests for commercial purposes, tourism and various other reasons. One of the unique features of Cyprus' habitats is the wild and sharp differences in elevations and habitats in different parts of the island as well as different climate conditions, all of which supply a diverse habitat for a unique array of fauna and flora.. Terra Cypria was established as a trust in 1992 to conserve the Cypriot environment and its biodiversity.
