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.
For male mosquitofish, sexual maturity is reached in about 43 to 62 days, but maturation age is also dependent on temperature and resources. [37] Female mosquitofish reach sexual maturity in about 21 to 28 days if born early within the reproductive season. The lifespan of a mosquitofish averages less than a year and the maximum is about 1.5 years.
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 ...
Their scaly wings have four dark spots, which are less distinct in the male. [4] [5] Male Anopheles freeborni aggregate into swarms to attract potential mates.
