True or False: All adult mosquitoes feed on blood.

The statement is false because not all adult mosquitoes feed on blood. While it is true that certain species of mosquitoes, particularly females, require blood meals for reproductive purposes—such as obtaining the necessary proteins to produce eggs—males do not feed on blood at all. Instead, male mosquitoes typically feed on nectar and other plant juices, which provide the carbohydrates they need for energy.

Additionally, some female mosquitoes may primarily feed on nectar, especially those that are not in the reproductive stage. Therefore, the feeding habits of mosquitoes are generally determined by factors such as species, sex, and life stage. This complexity highlights the diversity of mosquito biology and feeding behavior, confirming that the correct answer is that the statement is false.
