Not all mosquitoes are the same. Different mosqutoes spread different viruses and bite at different times of the day. Some mosquito species bite during the day, such as those mosquitoes that can spread chikungunya, dengue, and Zika viruses. Other species of mosquitoes bite most often at dawn and dusk, including those that can transmit West Nile virus.
