How many times does a dragonfly's wing beat per minute

1 answer:

5 0

A dragonfly beats its wings about 30 times a second. This is necessary to allow the insect to keep itself airborne, due to the relative weight of its body. Luckily, dragonflies have two sets of wings, or they would have to work even harder to stay up in the air.
