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.
Dragonfly vision is thought to be like slow motion for humans. Dragonflies see faster than humans do; they see around 200 images per second. [80] A dragonfly can see in 360 degrees, and nearly 80 per cent of the insect's brain is dedicated to its sight. [81]
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 American rubyspot (Hetaerina americana) is a damselfly of the family Calopterygidae. Males have a lustrous red head and thorax. The abdomen of both genders is brilliant green. [3] The female may have either green or copper colored marks on the thorax. [4]
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.
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 ...
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).
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.
