True or False: Culex mosquitoes are primarily daytime biters.

Culex mosquitoes are not primarily daytime biters; instead, they are known for their activity during the evening and nighttime hours. This means that they typically feed at dusk and into the night when it is cooler and more humid. Their feeding patterns are adapted to these conditions, as it may enhance their chances of finding hosts while reducing the risk of desiccation.

In contrast, some other types of mosquitoes, such as Aedes mosquitoes, are more active during the day. Since Culex mosquitoes prefer to feed during evening hours rather than throughout the day, the statement in the question is false. Understanding the specific behavior of various mosquito species is crucial for effective mosquito management and prevention strategies, particularly in public health efforts aimed at reducing mosquito-borne diseases.
