Enallagma cyathigerum (common blue damselfly or common bluet) is a species found mainly between latitudes 40°N and 72°N; 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, and throughout Ontario in North America. The species reaches a length of 29–36 mm (1.1–1.4 in) with wings 18–20 mm (0.71–0.79 in) long.
