Many Odonata are relatively large insects, but wingspans range from 17 mm (some Agriocnemis damselflies) to 191 mm (helicopter damselfly Megaloprepus coerulatus. The largest dragonflies have a wingspan of up to 160 mm, but they are much more massive than any damselfly.
This is a list of species of damselflies and dragonflies recorded in Australia. Common names of species are linked, beside their scientific names. The list is split into two groups: damselflies (suborder Zygoptera) and other dragonflies (infraorder Anisoptera). Those groups are organized in Families and then Genera and 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 green darner is a large dragonfly; males grow to 76 mm (3.0 in) in length with a wingspan up to 80 mm (3.1 in). [9] [10] Females oviposit in aquatic vegetation, eggs laid beneath the water surface. Nymphs (naiads) are aquatic carnivores, feeding on insects, tadpoles, and small fish.
The species is a small damselfly, 35 millimetres (1.4 in) long, predominantly black with iridescent blue markings. The male resembles blue-tailed damselflies (Ischnura species) but is distinguished by its large, spaced eyes that are a deep red. It is very similar to the small red-eyed damselfly (Erythromma viridulum).
