Damselfly. Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies (which constitute the other odonatan suborder, Epiprocta) but are usually 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 ...
Coenagrionidae. Coenagrionidae or are a family of damselflies, also known as pond damselfies, in the order Odonata and the suborder Zygoptera. [ 2 ] 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.
Enallagma cyathigerum (common blue damselfly, common bluet, or northern bluet) is a species found mainly between latitudes 40°N and 72°N; [2] 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 (1.3 to 1.4 in).
Description. Ischnura elegans can reach a body length of 27–35 millimetres (1.1–1.4 in) and a wingspan of about 35 millimetres (1.4 in). Hindwings reach alength of 14–20 millimetres (0.55–0.79 in). [5] Adult male blue-tailed damselflies have a head and thorax patterned with blue and black. There is a bi-coloured pterostigma on the front ...
The larvae are much more sensitive to oxygen deficiency than the larvae of the banded demoiselle, and need sufficient oxygen saturation in the water. Waters with high levels of sediment and sludge are not a good habitat for the larvae. Another key factor for the occurrence of the larvae of the beautiful demoiselle is the temperature of the water.
Pyrrhosoma nymphula can reach a body length of 33–36 millimetres (1.3–1.4 in). [4] These large and robust damselflies show black legs and wing spots in both sexes. [4] Mature males have red eyes and a black thorax with red shoulder stripes in mature specimen, but yellow stripes in immature. In fact ante-humeral stripes change to red with age.
Calopteryx papilionacea Rambur, 1842. Male in North Carolina. The ebony jewelwing (Calopteryx maculata) 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.
Calopterygidae is a family of damselflies, in the suborder Zygoptera. [2] They are commonly known as the broad-winged damselflies, [3] demoiselles, or jewelwings. [4] 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 ...
