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.
Both damselfly and dragonfly nymphs ventilate the rectum, but just some damselfly nymphs have a rectal epithelium that is rich in trachea, relying mostly on three feathery external gills as their major source of respiration. Only dragonfly nymphs have internal gills, called a branchial chamber, located around the fourth and fifth abdominal ...
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 ...
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.
Damselfly is the title of a 2012 novel in the Faeble series by S. L. Naeole [70] and of a 2018 novel by Chandra Prasad. [71] Modern poems with the damselfly as a subject include a 1994 poem by August Kleinzahler, which contains the lines "And that blue there, cobalt / a moment, then iridescent, / fragile as a lady's pin / hovering above the ...
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 following species have been included in previous lists of Irish dragonflies, but are no longer regarded as having been reliably recorded: Willow emerald damselfly; Small red damselfly; Red-eyed damselfly; Golden-ringed dragonfly
The male variable damselfly has a distinctive "wine glass" marking on the second segment of the abdomen. This is a black U-shaped mark with a black line joining the segment's narrow terminal black band. [1] (This distinguishes it from the azure damselfly which has the U-shape but no line connecting it to the terminal band.) [1] Male forms
