Characteristics
''Aedes'' mosquitoes are visually distinctive because they have noticeable black and white markings on their bodies and legs. Unlike most other mosquitoes, they are active and bite only
during the daytime. The peak biting periods are early in the morning and in the evening before dusk.
As disease vectors
Members of the genus ''Aedes'' are known vectors for numerous viral infections, including
dengue fever,
yellow fever, the
Zika virus, and
chikungunya, which are transmitted by species in the subgenus ''
Stegomyia'' such as ''
A. aegypti'' and ''
A. albopictus''. Infections with these viruses are typically accompanied by a fever, and in some cases, encephalitis, which can lead to
death
