Damselflies have a variety of internal and external parasites. Particularly prevalent are the gregarine protozoans found in the gut. In a study of the European common blue damselfly, every adult insect was infected at the height of the flying season. When present in large numbers, these parasites can cause death by blocking the gut. [22]

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.
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 ...
