How long can mosquito eggs survive in a dry state?

Mosquito eggs have a remarkable ability to endure harsh, dry conditions, which is crucial for their survival and reproduction. When faced with dry conditions, many species of mosquitoes can enter a state of dormancy, allowing their eggs to last for several months to over a year without water. This adaptation is vital, as it enables them to withstand periods when suitable conditions for hatching are not present, waiting for the return of moisture—usually from rainfall or flooding.

The longer survival time of mosquito eggs in a dry state helps ensure the continuation of the mosquito population, as it allows them to emerge when conditions are favorable for their development and feeding. By going into this dormant state, the eggs remain viable, poised to hatch when the environment becomes conducive to their survival, significantly contributing to the resilience of mosquito populations.
