Basically, habitat of dragon fly are in the nearest areas where is the clean water exist as like in forests, kaleyards, farms, rivers or lakes. Dragon fly can be stay also in our house once in our house has clean water area as like in my house' small garden. We can also find dragon fly in the mountains in 3,000 metres heights or in the sea shore.

The life cycle os dragon fly, start from eggs to grown up as we see grown up dragon fly above is about 6 months of ages. They like to lay their eggs amongst the hydrophytes inside the water but some of them they can lay the eggs in the rushing waters areas. Most of the times they spent inside water when the dragon flies still in shape of nymphs. They become frey for frog tadpoles and fishes. However when they are grown up, dragon flies become predators for hunting smaller animals such as mosquitos, flies, or bees.

  1. Head, in the part of its head : there is multifaceted eyes. Don't we notice it that they have big eyes? In these multifaceted eyes have thousand lenses terms as like we can find in the bees. That's the reason why dragon flies can be able seeing from many directions and so sensitive. It is the reason too that hard sometimes to caught dragon fly even we try to caught them from its behind. Look above the picture of the eyes
  2. Thorax. In this part, we can find the 3 pairs of legs and 2 pairs of  wings in it. At left and right side of the dragonfly's body. Although they have 3 pairs of legs, they can't walk properly. They just use their legs just to stand up and stick it in tree once they alighted in a tree when they don't want to fly. The one pair of front wings is bigger and longer than the second and the third wings. It is the reasons why dragon fly can fly with 97km/hour speed.
  3. Abdoment areas. In this part, dragon fly has ten segments and long size that make up such as needle. This part is very important for dragon fly, in here located digestion tool, respiration tool, reproductive tool and heart.

  • Anisoptera / Dragon flies, they have bigger body than damselflies and when they alighted in tree the wings would stretched out to the side.
  • Zygoptera/Damselflies, they are smaller than dragonflies and the body is shape totally as like needle shape and when they perched to the tree, the wings closed together on its back fused.
