What type of eggs are laid by Anopheles?

• A. Single eggs with floats that are desiccation susceptible
• B. Single eggs that are desiccation resistant
• C. Eggs rafts that are desiccation susceptible
• D. Desiccation resistant eggs

Answer: (A)

Anopheles lay their eggs singly on the water surface, and each egg has a buoyant float so it sits individually rather than forming a raft. These eggs hatch when re-wetted and are not built to withstand drying, so they are desiccation susceptible. This contrasts with rafts of eggs seen in some other mosquitoes and with eggs that are desiccation resistant, which can survive dry periods.
