Dragonflies have two pairs of wings so there is no need to flap wings simultaneously.
They flap the wings about 30 times per second. The flying speed of a dragonfly can reach 100 km / h.
How to fly a dragonfly is similar to a helicopter; they can fly forward, backward, up, and down.
Dragonflies are also capable of flying off due to strong flying muscles and wings that can move independently.
