Adult dragonflies have an elongated body, which is divided into the three distinct body parts. These parts are head, thorax, and abdomen. Their size range from 0.5 to 6 inches long. They have six legs, which are directly attached to its thorax. But, they are not good Walkers.
Dragonflies are equipped with two compound eyes like many other insects. These eyes help them to see all around except backward. They have a pair of wings which is transparent in color. But, there are some species whose wings are marked with colorful lines.
Dragonflies are carnivorous (meat eater). They prey on other insects for their food and mostly eat mosquitoes, moths, and other smaller dragonflies. They have very sharp teeth for preying on insects, and mostly carry the prey with their legs. An adult dragonfly can eat more than 100 mosquitoes per day; more than a fifth of their own body weight.
Many of the dragonfly species are endangered and some are very close to extinction. Mostly because of human-caused actions, which includes clearance of forests and development of hydroelectric dams. These actions have decreased the suitable habitats for their growth and development.
