Damselflies, both nymphs and adults, are eaten by a range of predators including birds, fish, frogs, dragonflies, other damselflies, water spiders, water beetles, backswimmers and giant water bugs. [22] Damselfly grooming Water mites parasitizing Pseudagrion decorum. Damselflies have a variety of internal and external parasites.
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 ...
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 ...
Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder and are similar in body plan, though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, along or above the abdomen. Dragonflies are ...
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 ...
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.
Damselflies are often confused with dragonflies, because they both belong to the order Odonata and share similar identifiable features. [10] A major distinguishing factor between a damselfly and dragonfly is the wing position when resting on a surface: damselflies fold the wings vertical and upright, as opposed to dragonflies leaving them ...
