Predators of mosquitoes can be divided into aquatic and terrestrial categories. Mosquitoes have a completely aquatic life as they hatch from an egg and then proceed through larval and pupal stages. Water is necessary for the immature mosquito to develop into an adult. In the water column, a set of predators threaten the continued growth of the mosquito. After a metamorphosis, the mosquito has an entirely new form, exhibiting structures allowing for flight and mouthparts for taking a bloodmeal. In their new environment, the fight for survival continues with a new set of predators interested in feeding on the adult mosquito.
