Which statement describes Aedes mosquitoes?

The statement that describes Aedes mosquitoes accurately indicates that they are vicious biters that feed at all times of the day. Aedes mosquitoes, particularly species like Aedes aegypti, are known for their aggressive feeding behavior and can bite during both daytime and nighttime hours. Their habit of feeding during the day, especially in the early morning and late afternoon, makes them particularly effective transmitters of diseases like dengue fever, Zika virus, and chikungunya.

In contrast to other species of mosquitoes that may prefer specific feeding times or have more limited activity periods, Aedes mosquitoes are adaptable and opportunistic, allowing them to exploit a variety of feeding opportunities. This characteristic significantly increases their potential to spread vector-borne diseases, posing a risk to public health.

The other statements do not accurately represent the behavior of Aedes mosquitoes and therefore do not hold true in the context of their feeding patterns or ecological traits. For instance, some species may exhibit nocturnal or crepuscular behavior, but Aedes are known for their daytime activity. Similarly, they are not solely attracted to animals, as they also feed on humans, which enhances their role as disease vectors.
