While it nay seem that all mosquitoes are bitters,this is not actually the case.Male mosquitoes eat plant nectar.On the other hand,female mosquitoes feed on animal blood.They need blood to live and produce eggs.When female mosquito bites a human being,it transmits a small amount of Saliva into the blood.This saliva may or may not contain a deadly disease.The result of the bite can be as minor as an itchy bump or as serious as death
