Which species of mosquitoes deposit their eggs on damp soil?

The choice identifying Aedes and Psorophora as species that deposit their eggs on damp soil is accurate because both of these genera have life cycles that involve such a habitat.

Aedes mosquitoes are known for laying their eggs above the waterline in areas that become flooded, especially in temporary bodies of water like puddles. This method of egg-laying enables them to take advantage of habitats that may not be consistently present, ensuring that their eggs will hatch when conditions are favorable.

Psorophora mosquitoes also share this behavior, often laying eggs in moist areas that could include roadside ditches or floodplains, where eggs can remain dormant until the soil becomes inundated with water.

In contrast, while other genera such as Culex and Anopheles have their own distinctive patterns of egg-laying, they tend to prefer standing water for their egg deposition, so they do not fit this specific criterion. Understanding the behavior of these various species helps in implementing effective mosquito control strategies by targeting their breeding sites appropriately.
