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]

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.
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.
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.
Enallagma cyathigerum (common blue damselfly or common bluet) is a species found mainly between latitudes 40°N and 72°N; [2] It is widely distributed in the Palearctic, common in all European countries (including Portugal, Spain, France, Great Britain, Ireland, Germany, Sweden, Norway, Finland, Poland, etc.) and in Asia in Turkey, Iran ...
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 ...
