Enallagma cyathigerum (common blue damselfly, common bluet, or northern bluet) is a species found mainly between latitudes 40°N and 72°N;[2] It is widely distributed in the Palearctic, and the Nearctic species Enallagma annexum was at one time considered to be synonymous with it. The species can reach a length of 32 to 35 mm (1.3 to 1.4 in). It is common in many different countries including Russia, Sweden, Norway, Finland, the United States of America, and South Korea.[3][4] Damselflies are an important link between the health of the aquatic ecosystem and its response to climate change.[5]
