What is the primary characteristic of a permanent water mosquito?

The primary characteristic of a permanent water mosquito is that it requires standing water for breeding. This type of mosquito thrives in habitats where water pools remain for extended periods, allowing them to lay eggs and for their larvae to develop successfully. The presence of stagnant water is crucial, as it serves as an ideal environment for their life cycle, providing both nourishment and protection for the developing mosquitoes.

The other choices refer to different characteristics that are not typical of permanent water mosquitoes. For instance, breeding in temporary water sources suggests adaptability to more ephemeral conditions, while exclusive development in tree holes narrows their habitat significantly. Being found only in urban areas is also limiting, as many species of mosquitoes associated with permanent water habitats can thrive in rural or suburban settings as well. This understanding emphasizes the ecological adaptations of permanent water mosquitoes and the critical role of stagnant water in their life cycle.
