Where do floodwater species of Aedes and Psorophora usually deposit their eggs?

Floodwater species of Aedes and Psorophora mosquitoes typically deposit their eggs on damp earth. These species have adapted to lay their eggs in locations that are subject to periodic flooding. When rain or floodwaters arrive, the eggs can hatch into larvae. The choice of damp earth is crucial because it provides a suitable environment for the eggs to survive until the water returns, allowing the life cycle to continue.

In contrast, still water bodies typically harbor other mosquito species that require standing water for their eggs to hatch. Soil under plant roots and leaves of plants may not offer the right conditions or exposure, making damp earth a more favorable choice for the reproductive strategies of floodwater mosquito species.
