What role does humidity play in mosquito behavior?

Humidity is a critical factor influencing mosquito behavior, particularly in relation to breeding activity. High levels of humidity create an optimal environment for the survival of mosquito larvae, as they thrive in moist conditions. This increased moisture also encourages adult mosquitoes to engage in mating and laying eggs because it ensures that the water bodies necessary for their reproduction remain viable. When humidity levels are higher, adult mosquitoes are less likely to desiccate, promoting longer lifespans and greater reproductive potential, which in turn enhances overall breeding activity.

The other options do not accurately represent the impact of humidity on mosquito behavior. For example, humidity does not reduce flight distance; in fact, mosquitoes are more likely to be active and travel further in humid conditions where they can efficiently obtain resources. It also does not eliminate adult mosquitoes; while extreme conditions can affect their survival, typical humidity levels do not have this effect. Additionally, while predators may find habitat in moist environments, humidity itself does not directly provide such a habitat; rather, it helps sustain the mosquito populations by supporting their breeding needs.
