Researchers at the University of South Dakota have released the federally endangered dragonflies that were raised in a laboratory over past few years.

Dragonflies are very important and beneficial to us and the environment thus, it is only just right to save these endangered dragonflies from extinction.
They have been raised at the University of South Dakota and now the scientists there will get to see what will the work of half a decade amount to.
So far this week, Soluk has released three out of 20 possible dragonflies at a forest preserve. Not more than 320 of the insects are left alive in Illinois, they said.
Soluk said, “We are trying to maximize their survivorship in captivity”. By growing them in the lab, the insect’s chance of survival is increased in such a way that 100 or even 200 from the same group reach “all the way to where they’d be ready to emerge into adulthood”.
The Hine’s pea green dragonflies, that will medical scientists thought to be extinct, are cautiously lifted among the lab conditions of University of South Dakota for 5 yrs. The idea that these dragonflies were extinct was eradicated in 1988, when an adult specimen was found and collected in the Des Plaines River Valley in Illinois.
The Hine’s emerald dragonfly was added in the U.S. List of Endangered and Threatened Wildlife and Plants on January 26, 1995. The reason for using a dragonfly from southwest Wisconsin is that researchers noticed that it had the same diverse genetic composition as the endangered dragonflies that have been found in Illinois.
Female Dragonflies keep their ealier delicious eggs by sinking the end of the body into a trivial drinking water. The eggs, known as nymphs, are hatch during spring.
Later, they crawl out of the water, shed their skin for the last time and emerge as flying adults.
“You may have lots of numbers, but if they’re genetically nearly identical, that means there’s not as much ability to resist something like a disease that comes along or that they just won’t have as much flexibility in terms of quick responses to things like change in conditions”, Soluk said. During that time they breed and lay new eggs before dying.
The scientists collected the eggs from a dragonfly in Southern Wisconsin to preserve their species. He thinks that the intrinsic beauty of the creature makes it worth saving and that we owe it to our successors to do so.

While the Hine’s emerald dragonfly may not play a vital economic or ecological role, that is not the point according to Mike Grimm of the Nature Conservancy. Some species, what is their value?
