You may be surprised to learn that there are more than 50 kinds of mosquito in the Upper Midwest.  We have chosen just a few of these to profile here. All of these species impact our lives either because they are nuisances that disrupt our outdoor activities, or because they transmit diseases like West Nile virus.

Even though this is only a small subset of Midwestern species, if you look closely at the pictures you can note many differences in color patterns and structures between the species.  Click on an image to learn more about the habits, habitats, and disease transmission potential of each mosquito species.  Click on a disease to learn more about the biology, prevention, and treatment of that mosquito-borne disease.

It can be hard to create accurate lists of the mosquitoes that can be found in each state, since species of mosquitoes regularly move into new areas and many parts of the Midwest have never been scouted for mosquitoes.

However, here are a few attempts from researchers and public health officials around the region to provide more information about what mosquitoes can be found in each state:
