Mosquito Life Cycle. Mosquito, After Feedings. The length of the mosquito life cycle varies between species and is dependent upon environmental conditions such as temperature and moisture. However, the life cycle of all mosquitoes is comprised of the egg, larval, pupal and adult stages.Male mosquitoes feed on plant nectar alone, while females extract the blood of hosts in order to develop and nourish eggs.
