Mosquitoes can develop from egg to adult in hot weather in as few as five days, but it may take up to a month. [13] At dawn or dusk, within days of pupating, males assemble in swarms, mating when females fly in. [14] The female mates only once in her lifetime, attracted by the pheromones emitted by the male.

The diseases they vector include arbovirus infections such as West Nile virus , Japanese encephalitis , or St. Louis encephalitis , but also filariasis and avian malaria .

Plant evolution may have played a role in the feeding divergence between male and female mosquitoes. At the time when these two mosquitoes became stuck in tree sap that eventually became amber ...
An individual mosquito can be heard across 2–5 cm in distance when sound level rises to 22-25 dB. [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.
Eggs produced by a female after a romp with a sterile male don't hatch. And female mosquitoes typically mate only once, meaning all her eggs are spoiled, so to speak. Vector experts say the ...
The Asian tiger mosquito has a rapid bite and an agility that allows it to escape most attempts by people to swat it. By contrast, the male member of the species primarily feeds on nectar and does not bite. The female lays her eggs near water, not directly into it as other mosquitoes do, but typically near a stagnant pool. However, any open ...
