Mosquito maps

The vector distribution maps are published regularly on the website to provide the ECDC stakeholders and the general public with the most up-to-date information on vector distribution, showing the distribution of the vector species at ‘regional’ administrative level (NUTS3).

Please note that the maps do not represent the official view or position of the countries. 

Exotic mosquitoes: Distribution maps

The maps shows the current known distribution of invasive mosquito species in Europe at ‘regional’ administrative level (NUTS3). They are based only on confirmed data (published and unpublished) provided by experts from the respective countries as part of the VectorNet project.

Separate maps for the distribution of each of the following mosquito species are currently available:  Aedes aegypti, Aedes albopictus, Aedes japonicus, Aedes atropalpus and Aedes koreicus.

Exotic mosquitoes: Surveillance map

The map 'Invasive mosquitoes' shows the current known vector surveillance activities in Europe. The surveillance activities include not only specific surveillance studies but also work done as part of on-going control activities, research projects and inventory studies.

For exotic species the possible distribution statuses are:


  • Established: An established population (evidence of reproduction and overwintering) of the species has been observed in at least one municipality within the administrative.
  • Introduced: The species has been introduced (but without confirmed establishment) in the administrative unit/study area.
  • Absent: Field surveys or studies on mosquitoes were conducted and no introduction or no established population of the species have been.
  • No data: No sampling has been performed and no data on the species is available.
  • Unknown: It is unknown whether there are field studies on this species.

Join VectorNet and submit data

ECDC and EFSA, through the VectorNet network, continues to improve the data collection for the maps. VectorNet is looking for vector-borne disease experts who are interested in sharing data on the distribution of mosquito, tick, sand fly and culicoides vectors. Experts can contact VectorNet at to join the network. They can also register and upload data to the common database through the VectorNet tool.
