12 Fascinating Facts About the Dragon Fly
Dragon flies are insects of the order Odonata. About 4,870 species of the dragon fly are known to exist all over the world but they are especially common in tropical areas. Generally, dragon flies range in length from two to twenty centimeters, but the Meganeura monyi – which flourished in the Carboniferous period more than 250 million years ago – had a wingspan of more than 70 cm and was the largest insect ever known to exist on the Earth. Here are some fascinating facts about the dragon fly.
- Dragon flies are among the most powerful and versatile of all flying insects clocked up to 95 km/h.
- They can lift more than double their own weight – an achievement that man-made aircraft cannot approach.
- Dragon flies can take off backwards, accelerate very rapidly, execute an unbanked turn in forward motion, come to a dead stop in an instant, hover, and even somersault in the heat of combat.
- The US Air Force has actually funded wind-tunnel research on dragonflies on how they do it.
- One-third to one-half of a dragon fly’s body is devoted to flight muscles and they out power all other winged insects in flight.
- Each of the dragon fly’s bulbous eyes contains up to 30,000 lenses, and its field of vision encompasses nearly 360 degrees.
