The annoying noise emitted by mosquitoes is due to their rapid fluttering of wings ; this very fast movement (300 to 600 times per second) allows the insect to fly, covering up to three kilometers in an hour.
According to some scientists, the sound frequencies emitted during the hum represent an amorous call . The male flaps his wings so as to emit high-frequency sounds, followed by the female who begins to buzz in turn to try to tune into the suitor's tone.
