Where are the larvae of salt marsh mosquitoes typically found?

The larvae of salt marsh mosquitoes are commonly found in depressions within salt marshes. These habitats provide the necessary conditions for mosquito larvae to thrive, including brackish water that is characteristic of salt marsh environments. The shallow, stagnant water in these depressions is an ideal breeding ground, as it protects the larvae from many predators and allows them to feed on organic matter and microorganisms present in the water.

In contrast, the other locations mentioned, such as urban pools or freshwater lakes, are less suitable for salt marsh mosquito larvae due to differences in salinity and habitat structure. Open fields typically do not retain water crucial for mosquito reproduction, making them an unlikely environment for larvae. This makes depressions in salt marshes the most appropriate and natural habitat for salt marsh mosquito larvae.
