The ones that look like males, andromorphs, are usually under a third of the female population but the proportion can rise significantly and a theory that explains this response suggests that it helps overcome harassment by males. [7] Some Coenagrionid damselflies show male-limited polymorphism, an even less understood phenomenon. [8]
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 ...
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.
These damselflies can easily be confused with small red damselflies, but the latter has orange legs, while the large red damselfly has black legs. In Greece and Albania a closely related species occurs, the Greek red damsel (Pyrrhosoma elisabethae). They look very much the same, the females only having a slightly different pronotum with deep ...
Damselflies are odonates in the suborder Zygoptera. There are 4 superfamilies: Calopterygoidea, Coenagrionoidea, Hemiphlebioidea and Lestoidea. There are 4 superfamilies: Calopterygoidea, Coenagrionoidea, Hemiphlebioidea and Lestoidea.
It is a medium-sized damselfly with pale blue eyes, dark on top. They grow to 38mm in length. Its thorax is azure blue with black, broad dorsal stripes and narrow humeral stripes. Abdominal segments 1 and 2 are blue with black marks on the dorsum. Mark on segment 2 looks like a chalice or thistle-head. Segments 3 to 7 are black on dorsum and ...
The adult damselflies prey on small flying insects, caught using their legs like a basket to scoop the prey up while flying, or insects taken from leaves. Damselfly nymphs are aquatic, and prey on small aquatic insects or other aquatic larvae. A male can try to interfere with a mating pair, by attaching itself to the mating male.
