Dragonflies are strong fliers with fairly robust bodies and they have wings that are broad near the base; at rest the wings are held out to the side. Damselflies tend to be less robust, and appear weaker in flight; their wings are narrow near the base and (in most species) held folded back over the abdomen when perched.
The chasers, darters, skimmers and perchers and their relatives form the Libellulidae, the largest family of dragonflies. [2] It is sometimes considered to contain the Corduliidae as the subfamily Corduliinae and the Macromiidae as the subfamily Macromiinae. Even if these are excluded (as Silsby does), there remains a family of over 1000 species.
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 ...
Common names are those given in the standard literature; where a different name has been given in The Natural History of Ireland's Dragonflies, this is given in brackets. [1] Most of these species are resident, others are vagrants and some have not been recorded since the nineteenth century.
There are 57 recorded species of Odonata in Britain, made up of 21 damselflies (suborder Zygoptera) and 36 dragonflies (suborder Anisoptera). Of these, 42 species (17 damselflies and 25 dragonflies) are resident breeders, and the remainder are either extinct species, or vagrants - in respect of the latter, this list follows the decisions of the Odonata Records Committee.
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 ...
The common darter (Sympetrum striolatum) is a dragonfly of the family Libellulidae native to Eurasia. It is one of the most common dragonflies in Europe, occurring in a wide variety of water bodies, though with a preference for breeding in still water such as ponds and lakes. In the south of its range adults are on the wing all year round.
Trithemis is a genus of dragonflies in the family Libellulidae.They are commonly known as dropwings.There are over 40 species, mainly from Africa; two are endemic to Madagascar, and five can be found in Asia. [1]
