Where do Culex, Culiseta, and Anopheles mosquitoes lay their eggs?

Explanation:
Egg-laying by these mosquitoes happens on the surface of standing water. The eggs are laid so they immediately contact water as they hatch. Culex and Culiseta typically produce floating rafts or clusters, while Anopheles lays individual eggs that sit on the water surface. This is why describing their egg-laying as on the water surface—in clusters, rafts, or singly—fits all three genera. Eggs buried in mud, tucked into soil, or placed on tree bark wouldn’t provide the aquatic environment the larvae need to emerge.
