Dragonflies in Public Life Cycle.

Dragonfly life cycle from egg to death as an adult. This dragonfly age varies between six months and a maximum of six or seven years. However, only a few weeks (up to 4 months) who lived as an adult dragonfly.
In general, there are three stages of the life cycle of the beautiful insects. Ie egg, nymph, and ended up as an adult dragonfly. Most of their life cycle is spent when the new becomes an angel. Nymphs are young insects which have the same nature and form of the adult insects. Nymphs choose to live in the water.
Here are the stages through which stopped dragonfly from egg to adult.

1. Egg.

At this stage is characterized by female dragonflies lay eggs after mating with males doing. Typically, the female lays her eggs on the host plant twigs that fall underwater. However, there is also a female parent who simply put their eggs in the water.
This insect has an emotional attachment is high. Sometimes, the male parent accompanied the female parent when they wanted to release their eggs in water. Although not able to accompany directly, there is also a male parent who chose supervise from a distance when the release of the egg takes place.
In essence, the male will not go away after marrying the female. And will always accompany the mother during the process of egg release. This insect deserve loyalty imitated human.

2. Nimfa.

The release of the egg before hatching, usually takes 7 to 14 days. After hatching, the larvae of dragonflies are called nymphs. At this time, this insect is transformed into a ferocious carnivore. In fact, for large nymphs able to prey on tadpoles and fry.
This insect nymphs breathe like a fish. They breathe using gills are located in the rectum at the end of the abdomen. On the type of needle dragonfly nymphs, they breathe using gills 3 shaped like feathers and is also located at the tip of her abdomen.
At this stage, the nymph will stay alive in the water until it becomes quite large. Just as snake, insect nymphs will go through several rounds of skin turnover or commonly called ecdysis. Each stage in the process of changing the skin itself is called instars.
Instar can reach 8 to 17 times the stage. It all depends on the type of species nymph. Medium age nymph itself can reach 28 days. In fact, there are up to a few years. In the next process, instar who felt it had enough time to creep out of the water. Then, remove the skin as well as out in the adult form.

3. Imago.

At the time of the nymph is completely developed and supported by environmental and weather conditions that favor, he will automatically complete the stages of his life as an adult dragonfly. The process as described above. That aa would crawl out of the water, looking for twigs for a foothold, and then release the skin. Skin nymphs called the exuvia. After this release, young adult dragonfly ready the next life.
Several types of these insects perform "rituals" release the skin at night. I wonder why. Or perhaps there are some types of dragonfly superstitious by releasing the skin at night. But clearly, this process merely as a preparation for the next day the young adult dragonfly is ready to fly on a sunny morning.
In the next process, these insects reach adulthood perfect shape and start the "hunt" looking for mating partners. In addition, he should also look wet. Adult dragonfly environment has only a short life, which ranges from 240 days. After that he was dead.
In the Green Darner dragonfly life cycle, the entire process or life stage of the life cycle of the dragonfly same as other types. So, what distinguishes it from other types of skin color alone only. If my friends see the picture of this insect species, indeed we will be amazed by the beauty of the color of the body and wings.
