What pattern do Culex, Culiseta, and Anopheles lay their eggs in?

• A. In above-water nests on vegetation
• B. Buried in mud near shorelines
• C. On the underside of leaves
• D. In clusters, rafts, or singly on the water surface

Answer: (D)

Egg-laying patterns among mosquitoes are tied to where the eggs sit and how they’re arranged on water. Culex and Culiseta typically lay eggs in floating clusters called rafts on the water surface, forming visible groups that rest on top of the water. Anopheles lays its eggs singly on the water surface, not as a raft. So the characteristic they share is that all their eggs are placed on the surface of water, with different genera using either rafts, clusters, or individual eggs. The other options describe habitats that aren’t how these mosquitoes lay eggs, making the water-surface pattern the correct concept.
