Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the Epiophlebia damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and ...
The Odonatoptera are a superorder (sometimes treated as an order) of ancient winged insects, placed in the probably paraphyletic group Palaeoptera.The dragonflies and damselflies (which are placed in the subgroup Odonata) are the only living members of this group, which was far more diverse in the late Paleozoic and contained gigantic species, including the griffinflies (colloquially called ...
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 the body.

Males also have secondary genitalia (including the anterior lamina, hamuli and posterior lamina) on S2 and S3. Female damselflies and some dragonflies have a strong ovipositor on the underside of S8 and S9, but in many dragonflies the egg-laying apparatus is merely a spout, a basket, or a pair of flaps. Some species have foliations (leaf-like ...

Orthetrum sabina, the slender skimmer [1] or green marsh hawk, [3] is a species of dragonfly in the family Libellulidae. [ 4 ] [ 5 ] It is widespread, being found from south-eastern Europe and North Africa to Japan and south to Australia and Micronesia .
Members of this genus are medium-sized dragonflies with dark bodies and a metallic green lustre. The eyes are brilliant green, and many species have dull to bright yellow markings on the thorax and/or abdomen. The abdomens of males are distinctive, with the first two segments bulbous-shaped, the third constricted, and the rest of the abdomen ...
