What is a key characteristic of Aedes aegypti in relation to human behavior?

Aedes aegypti is known for its biting behavior primarily during daylight hours, particularly in the early morning and late afternoon. This characteristic makes them notably different from many other mosquito species that tend to be more active during the night. Their feeding habits have adapted to align with human activities, allowing them to effectively transmit viruses such as dengue, Zika, and chikungunya, which are significant public health concerns. This daytime activity, coupled with their close relationship to human habitation, enhances their status as competent vectors of these diseases.

The other options do not align with the established behavior of Aedes aegypti; they do not limit their biting to the night, they do not predominantly feed on animals, and humans are one of their primary hosts.
