Full Answer

Only female mosquitoes suck blood. Although mosquitoes derive their energy and nutrients from sugary fluids, such as nectar and honeydew, their eggs require the abundance of protein found in blood. The saliva of a mosquito blocks clotting of the blood, allowing easier access. During feeding, a female mosquito can ingest her entire body weight in blood.
