Damselflies have slenderer bodies than dragonflies, and their eyes do not overlap. Damselfly nymphs differ from dragonflies nymphs in that the epiproct and pair of paraprocts at the tip of their abdomen has been modified into caudal gills, in addition to being able to absorb oxygen through the wall of their rectum, whereas dragonflies breathe ...
At night, the damselflies will return to the same sunlit areas within the vegetation where they started their day. Male beautiful damselflies do not range far from their breeding, hunting, and resting areas, only going a relatively small 20–100 metres (66–328 ft). Females have been observed flying distances of up to 4 miles (6.4 km) per day.
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.
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 first aircraft of the type was the Santos-Dumont No. 19, which was built in 1907 to attempt to win the Grand Prix d'Aviation offered for a one kilometre closed-circuit flight. Powered by a 15 kW (20 hp) air-cooled Dutheil & Chalmers flat-twin engine mounted on the leading edge of the wing, it had a wingspan of 5.1 m. (16 ft 9 in), was 8 m ...
Damselfly nymphs have a different food source within the freshwater streams as opposed to on land and in the air, including tadpoles, aquatic invertebrates, small fish and other damselfly nymphs. [19] Although similar to the adult damselfly, the prey is dependent on the individual’s size and only consists of smaller species. [12]
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 common flatwing (Austroargiolestes icteromelas) is a very common species of damselfly of the subfamily Argiolestinae in the family Argiolestidae. [3] [4] It is also known as an Australian flatwing. Both male and female common flatwings look similar, with a long and slender body about 43 mm in length, and a bright metallic-blue colour.
