This individual carries three small parasitic midges (Forcipomyia paludis) gripping the membrane of its wings. These tiny dipteres attach themselves so firmly to the odonate's wings that they hold themselves even during the flight of the dragonfly. They feed by sucking the hemolymph (the blood of insects) that circulates in the veins of the wings.
