What is the lifespan of an adult mosquito in ideal conditions?

The lifespan of an adult mosquito in ideal conditions is typically between 2 to 4 weeks. This duration allows for sufficient time for mosquito adults to go through their life processes, which include feeding, mating, and laying eggs. Environmental factors such as temperature, humidity, and availability of food sources can significantly influence this lifespan. Under optimal conditions, mosquitoes can thrive, but they are also subject to various natural threats that can shorten their lives, such as predators, diseases, or changes in environmental conditions.

The other options either underestimate or overestimate the typical lifespan of adult mosquitoes when conditions are favorable. For instance, saying 1 week would be too short, as many species can live at least twice that long. The ranges of 5 to 10 weeks or more than 10 weeks, while possible under the right circumstances for some species, are not the baseline lifespan that is commonly observed across various types of mosquitoes. Thus, the choice of 2 to 4 weeks accurately reflects the most common adult lifespan in ideal conditions.
