Which statement correctly identifies a defining behavioral trait of Aedes mosquitoes?

• A. Aedes – Day-biting and container breeding.
• B. Anopheles – Day-biting and malaria vector.
• C. Culex – Crepuscular/nocturnal and breeding in running water.
• D. Anopheles – Crepuscular biting.

Answer: (A)

Aedes mosquitoes are best recognized by two behavioral patterns that are particularly reliable for identifying them: they bite during the day and they breed in small water-filled containers around human habitats. This daytime feeding habit sets them apart from many other mosquitoes that mainly bite at dusk or at night. Their container-breeding habit means their immature stages develop in cups, tires, flower pots, gutters, and other small vessels holding standing water, which is a hallmark of how these species proliferate in urban areas. Anopheles mosquitoes, which transmit malaria, are more active at dusk or night and do not rely primarily on small containers for breeding. Culex mosquitoes often breed in stagnant or polluted water and can be active around twilight or at night, not typically in running water. Anopheles biting at crepuscular times is true for some species but does not define their behavior as clearly as the daytime biting of Aedes. So the combination of day-biting and container breeding most accurately describes Aedes.
