What is a characteristic of certain mosquito eggs?

Certain mosquito eggs possess the ability to float on water, a characteristic attributed to the presence of specialized spines or projections that enable them to trap air. This adaptation is particularly advantageous as it helps keep the eggs buoyant, allowing them to remain on the surface of the water where they can hatch when conditions are favorable. Floating eggs are often found in areas with stagnant water, which serves as an ideal habitat for mosquito larvae once the eggs hatch.

While other characteristics may vary among mosquito species, such as the arrangement in which eggs are laid or their size, floating eggs are a distinctive trait that enhances their survival by ensuring they remain at or near the water's surface, thereby increasing the likelihood of successful hatching and development into the aquatic larval stage.
