Culux larvae inhabit which type of water environment?

• A. Ocean water
• B. Fast-moving streams
• C. Still stagnant water
• D. Desert sand

Answer: (C)

Mosquito larvae like Culex need a calm aquatic environment in which to develop. They thrive in still, stagnant water such as ponds, ditches, and containers where there isn’t strong flow to sweep them away. They breathe at the surface with their siphons, so a steady, quiet water surface is important for their survival and growth. In fast-moving streams, the current would prevent them from staying at the surface and hinder their development. Ocean water is too salty and dynamic for typical Culicine larvae, and desert sand isn’t a water habitat at all. So still stagnant water is the environment that best fits their life cycle.
