Which environment is described as having eggs deposited on the waters surface?

• A. Permanent pool environments
• B. Transient water environments
• C. Flood water environments
• D. Desert oases

Answer: (A)

Eggs deposited on the water surface in floating rafts point to species that favor permanent, still bodies of water. Culex mosquitoes lay eggs in rafts that float on the surface, and permanent pools provide the stable, long-lasting habitat needed for those rafts to remain on the water and for the larvae to develop. In contrast, transient pools dry up quickly, so they’re more typical of mosquitoes that lay eggs in containers or on damp surfaces rather than in surface rafts. Floodwater environments are dynamic and favor different oviposition strategies, and desert oases are irregular and less reliable for raft eggs. So the environment with eggs on the water surface aligns with permanent pool environments.
