| The black-lined skimmer prefers rocky edges of water with many stones, sand pits and loose reeds or rushes or standing water (lakes, ponds, pools) or beaches. Adults are found from June to September. They live off insects. The black-lined skimmer establishes a territory and the males occasionally patrol this near the surface of the water. Competing species of dragonflies are systematically expelled from the area. The black-lined skimmer is very shy and always maintains a greater flight distance. Females usually remain hidden in the riparian vegetation and only rarely appear. They hunt in the evening and can only be observed flying in daylight during the mating season.... | | |
