[100] Common mosquito-borne viral diseases include yellow fever [101] and dengue fever transmitted mostly by Aedes aegypti. [102]
Depending on the species, the adult Culex mosquito may measure from 4–10 mm (0.2–0.4 in). The adult morphology is typical of flies in the suborder Nematocera with the head, thorax, and abdomen clearly defined and the two forewings held horizontally over the abdomen when at rest.

[7] Male and female mosquitoes can also be distinguished by their wingbeat frequencies, which are 700–800 Hz for males and 400–500 Hz for females. [7] As a result, flight sounds are used to determine flight activity and distinguish sex of groups.
