Why do bugs buzz?

Answer 1

Well, it don't rub their wings, they don't rub their legs either as those caterpillars. The only thing that they can make sound is their butt. They always shake their butts like a rattle.

Answer 2

Why? Not sure.

How:

Bees buzz because they control their breathing through 14 valves on their body known as spiracles. Less than 1% of the noise comes from their wings.

Answer 3

It used to be thought it was the sound of the wings moving so rapidly. Now we know that it's actually the noise air makes as it rushes in and out of the spiracles, the breathing holes on a flies thorax.

Answer 4

they rub their wings together

I thought so too but actually, they don't. The male cicada has two ribbed membranes on each side of its first abdominal segment. By contracting the muscle, the cicada buckles the membrane inward, producing a loud click. As the membrane snaps back, it clicks again. The two membranes click alternately. Air sacs in the hollow abdominal cavity amplify the clicking sounds. The vibration travels through the body to the tympani, which amplify the sound further. They are the loudest insect noise. I researched this after I watched one making noise and realized the wings weren't moving.

Answer 5

Insects make buzzing sounds by beating their wings (fluttering) very fast.

The sounds can be used to attract other insects of the same species. They can be made during normal activity like flying (like mosquitoes). The differences in sound is cause by the differences in fluttering speed.

Note that some insects also rub their body parts together to make sounds; these sounds aren't considered buzzing, they're called stridulation. For example, crickets chirp by rubbing a file of pegs on their forewing against a scraper on the other forewing, & grasshoppers rub their legs against their wings.

Answer 6

The buzz that you hear is the bugs wings vibrating when it flies.

Or because they just want to annoy you!:)
