Which mosquito species is known for forming rafts of eggs?

Culex mosquitoes are known for their unique reproductive behavior of laying eggs in a raft-like structure. This characteristic helps the eggs remain buoyant on the water surface, which is advantageous for their development. In this raft formation, multiple eggs are adhered together, maximizing the likelihood that the larvae will access the water below for hatching.

In contrast, other mosquito genera, such as Anopheles and Aedes, have different egg-laying behaviors. Anopheles typically lays its eggs individually or in small clusters on the water surface, while Aedes often lay their eggs in dry areas or on the sides of containers, which could eventually be submerged. Carpomyia, while a valid mosquito genus, is not known for this particular egg-laying behavior and is not as prominent in mosquito control discussions.

Understanding these reproductive strategies can help in mosquito management and control efforts, providing insight into where and how to target interventions for specific mosquito populations.
