There are more than 3,500 species of mosquitoes and about 175 of those are found in the United States. Of the 175 found in the U.S., West Virginia has the least number of species of mosquitoes (28), while Texas has the most (85).

There are over 40 different genera of mosquitoes, but the 3 most common genera found in the United States are:

  • Aedes - Originally found in tropical and subtropical climates, this genus of mosquito has been seen everywhere, with the exception of Antarctica. They have white and black markings on their body and legs. They are active and only bite during the daytime.
  • Anopheles - Known as the Malaria mosquito, this genus lives in colder climates, but resides in tropical and subtropical climates; leading to the spread of the disease in Sub-Saharan Africa.
  • Culex - This genus of mosquito occurs worldwide except in north of 66° N/S and are the most common mosquito seen in the U.S. It bites typically at dawn and dusk. It’s one of the most persistent biters that leave behind painful, irritated skin rashes and welts.

Not all mosquitoes feed on humans. Many species of the insect will only draw blood from animals. For example, culiseta melanura bites birds almost exclusively, and rarely bites humans and uranotaenia sapphirina is known to feed on reptiles and amphibians.
