To explain the sound while flying, it depends on how many beats per minute (BPM) the insect needs to fly, and how big it is. To put it into a bit of perspective, a small yet high-revving V8 will sound completely different than a larger, lower-revving engine of the same configuration.

Cicadas have a unique organ called a tymbal that rapidly rattles chitinous ribs together via muscle contractions. It’s basically an organic percussion instrument.
