Dragonflies needle is an insect class that likes a place close to water. It could be said they were never far away with water. They can live all over the place, except for the north cover. The unique benefit based on the fact of the habitat of the dragonfly or Damselfly states that if a place or area is inhabited by them, it is marked with water in the area relatively clean.
Apparently in addition to these animals are eye-catching, they are also beneficial to human life. But I am not doing Damselfly research, but I want to include it in my macrophotography collection.
