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]
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.

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 Pseudostigmatidae are a family of tropical damselflies, known as helicopter damselflies, giant damselflies, or forest giants. The family includes the largest of all damselfly species. They specialize in preying on web-building spiders, and breed in phytotelmata, the small bodies of water held by plants such as bromeliads.
This common damselfly looks very like a common blue damselfly. The behaviour is also different - unlike common blues, they rarely fly out over large stretches of water. They are not normally as common around August and September, June and July being the peak of their populations.
These small green, black and blue damselflies have a slender body with four wings folding over the back. The thorax of the males is black above, with pale green sides and green shoulder stripes. Eyes are dark above, greenish below. Abdomen is mainly black, with thin pale rings.
