Dragon fly also known as helicopter insect locally, is the fastest flying insect in the world. Most dragonflies prefer to perch themselves close to water, and the length of time they remain perched can vary. Various species tend to have individual behaviors, and you could have dragonflies that prefer hanging on twigs, or flying very high off the ground, making it quite difficult to observe. Because of their compound eyes, dragonflies can see in many directions at once. This makes them very sensitive to movement. Female dragonflies lay their eggs in or near water, often on floating or emergent plants. The dragonfly eggs then hatch into nymphs. which is how most of the dragonfly's life is spent. The dragonfly nymphs live beneath the water's surface, using extendible jaws to catch other invertebrates or even vertebrates such as tadpoles and fish. The larval stage of large dragonflies may last as long as five years. In smaller species, this stage may last between two months and three years. When the larva is ready to metamorphose into an adult, it climbs up a reed or other emergent plant. Exposure to air causes the larva to begin breathing. The skin splits at a weak spot behind the head and the adult dragonfly crawls out of its old larval skin, pumps up its wings, and flies off to feed on midges and flies.
