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.
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 labium is folded under the body at rest and struck out at great speed by hydraulic pressure created by the abdominal muscles. [17] 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 ...
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 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.
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.
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
