How many species of mosquitoes in Minnesota bite humans?

• A. 5
• B. 15
• C. 50
• D. 30

Answer: (B)

Many mosquito species share the landscape, but not all of them seek humans for a blood meal. In Minnesota, host preferences vary by species, and only a subset regularly bites people. That means the number of human-biting species is smaller than the total number of species present. About 15 species are known to bite humans in Minnesota, which is why this option is the best fit among the choices. The other numbers don’t align with how mosquito ecology works here: five is too few given multiple human-biters exist; fifty would imply every species bites humans, which isn’t true; and thirty would suggest about half of the species bite humans, which overstates the typical distribution of host preferences in this region. Understanding that only a portion of species bite humans helps explain why nuisance and disease risk are driven by a limited set of mosquitoes, not by all species in the area.
