The last checklist of New Jersey mosquitoes was published in 1983 and contained 59 species from 10 genera. Since that time 4 additional species have been collected in New Jersey: Aedes thibaulti, Aedes infirmatus, Aedes aegypti, and Aedes albopictus. Aedes aegypti was not able to overwinter and is not part of New Jersey's mosquito fauna. As a result, the addition of 3 species brings the updated checklist of New Jersey mosquitoes to 62.
