Male Mosquitoes do not bite or eat blood, they eat flower nectar. They are easy to tell from the females because of their large, fuzzy antennae. They use their antennae to hear the female's wingbeats. If you tap a high C tuning fork and touch it to a balloon, you can hear what a female mosquito's buzz sounds like; it is at a frequency of 512 beats per second. A female mosquito's wings beat near that frequency.
