The Crescent Bluet is a very rare and beatiful damselfly. It was hoovering around me when I seen it. this crescent bluet is black with teal colored stripped markings all over its body.It is about 33mm long and the wingspan is about 38mm. Birds and fish feed on the irish damselfy and it eats other flying insects usually mosquitoes. They enter the world in tiny eggs once they hatch into larve the damselfly crawls around hunting for food under water.
