Which life stages of mosquitoes are considered to be aquatic?

The life stages of mosquitoes that are considered aquatic include the egg, larva, and pupa stages.

Mosquito eggs are typically laid in or near water sources, such as stagnant ponds, marshes, or containers. These eggs may hatch into larvae (commonly referred to as "wigglers"), which live in the water and rely on it for their development. During the larval stage, mosquitoes feed on microorganisms and organic material found in the water.

After the larval stage, mosquitoes enter the pupa stage, also known as the "tumblers." Pupal mosquitoes remain in the water but do not feed during this stage; instead, they prepare for their final transformation into adult mosquitoes. The entire process from egg to adult involves certain stages that necessitate an aquatic environment to complete their development.

In contrast, adult mosquitoes are predominantly terrestrial, emerging from the water to fly and reproduce. Hence, options that include only larva and pupa or any combination excluding the egg stage do not encompass the complete range of aquatic life stages.
