Culux larvae habitats include still stagnant water, polluted ponds, catch basins, flooded fields, and artificial containers. Which option is not a typical habitat?

• A. Flowing streams
• B. Still stagnant water
• C. Polluted ponds
• D. Artificial containers

Answer: (A)

Flowing streams are not typical habitat for Culex larvae because these mosquitoes favor still or slow-moving, nutrient-rich water where eggs and larvae can stay in place, feed on microorganisms, and develop without being swept away. The listed environments—still stagnant water, polluted ponds, catch basins, flooded fields, and artificial containers—provide stable, nutrient-rich pools that support their growth. In contrast, the movement and turbulence of flowing streams disturb the surface film, dislodge larvae, and reduce feeding opportunities, making them unsuitable for Culex development.
