Damselfly grooming Water mites parasitizing Pseudagrion decorum. 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.
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, Russia, and South Korea.

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 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.
Young adult female. This is a small to medium size damselfly (length up to 46 mm (1.8 in), wingspan up to 53 mm (2.1 in)). [3] The eyes are greenish with a dark grey cap. [4] As is the case in many damselflies, this species shows strong sexual dimorphism.

Adult males of Pacific Hawaiian damselfly populations are extremely territorial. They will guard specific areas in Kalo (Colocasia esculenta) field pools where females lay eggs. When copulating, males will grip the females behind the head using their claspers to protect their females from other males. Males will also exhibit this behavior when ...
The genus contains the following species: [3] [4] Calopteryx aequabilis Say, 1839 – River Jewelwing [5]; Calopteryx amata Hagen, 1889 – Superb Jewelwing [5]; Calopteryx angustipennis (Hagen in Selys, 1853) – Appalachian Jewelwing [5]
