Which mosquito life cycle stage does NOT typically survive in a terrestrial environment?

The larval stage of mosquitoes does not typically survive in a terrestrial environment because mosquito larvae are aquatic organisms. They are usually found in stagnant or slow-moving water, where they feed on microorganisms and organic matter. This aquatic habitat is essential for their development, as larvae breathe through specialized structures called siphons, which require water.

In contrast, eggs can be laid in moist areas and can tolerate temporary desiccation. Pupae, while also aquatic, are in a transitional stage and can survive in water until they emerge as adults. Adults can thrive in various terrestrial habitats, as they are capable of flying and can find food and breeding sites away from water. Therefore, the larval stage is distinctly dependent on an aquatic environment, making it the correct answer regarding which stage does not survive in terrestrial settings.
