This article reports data on the occurrence and spread of three invasive mosquito species: Aedes japonicus, Aedes koreicus, and Aedes albopictus in two regions of Northeast Italy; resulting from larval and adult collections performed during the 2011-2020 period in the framework of different projects. Routine species identification was performed using morphological characters and complemented by molecular methods when required. For the years 2019 and 2020, detailed data are reported which update previous information on municipalities and sites where these species have been detected. Geo-referenced information on the presence of invasive mosquitoes is reported and demonstrated on maps. Additional data on the nature of breeding sites and the finding of native mosquito species in the same collections are also provided.
