Bzzzz...bzzzzz....How do fies make that buzzing noise anyway? Do they have something hidden somewhere that makes the noise?
First of all, flies buzz only when they are flying. That is because the noise you hear is the sound of flies' wings. Those wings move very quickly-almost two hundred times each second. In face, they move so fast that they make a buzzing sound. Mosquitoes also make a buzzing sound when they fly. A mosquito's buzz, however, is not nearly as loud as a fly's.
The champion buzz maker, of course, is that very noisy insect called the bumblebee. In fact, the word bumble comes to us from an old word that means "humming." Isn't that what the flapping of a bee's wings sounds like?
