Having said that Bry they still have to puncture the skin first which may not be the conventional meaning of bite but have the same effect.

It is more like impaling than biting:
Only female mosquitoes bite, and all mosquitoes live on the sugar found in plant nectar, not on blood. But there is a reason females seek blood.
Female mosquitoes, unlike males, have a proboscis. This is a long thin needle-like built-in syringe located at the mouth. They use this to impale their victims, in order to fill their abdomens with blood. Proteins in the blood are necessary to produce fertile eggs. Since males cannot produce eggs they have no need for blood. Females require a new blood 'meal' for every nest they lay, and produce about 250 eggs per meal.
