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.
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 ...
It is a small damselfly with sky-blue eyes slightly capped with black. Its thorax is black on dorsum with two very broad antehumeral azure blue stripes bordered with black. The lateral sides are pale blue. Abdomen is pale blue marked with black on dorsum up to segment 7. Segments 8 to 10 are blue; segment 10 has a narrow mid-dorsal stripe.
It is the only damselfly in Europe to hold its wings straight out like a dragonfly. [2] The length of the rear wing is 30–34mm. The pterostigma is long (the length of five cells below) and dark blue-grey in males, white or gray in females. In both males and females, the wing tip is usually dark from the pterostigma, but the size of that spot ...
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.
Argia is a genus of damselflies of the family Coenagrionidae and of the subfamily Argiinae. It is a diverse genus which contains about 114 species and many more to be described. It is also the largest genus in Argiinae. They are found in the Western Hemisphere. They are commonly known as dancers.
(This distinguishes it from the variable damselfly where the U-shape is joined to the terminal band with a black line.) Segments three to five are blue with broader black terminal bands, lacking the forward-pointing projection the upper surface which adult male common blue damselfly has. Segment six has a similar pattern but with more ...
