Native mosquitoes
These maps show the distribution and surveillance of vectors at ‘regional’ administrative unit level - NUTS3 or equivalent and NUTS2 in Austria, Belgium, Denmark, Germany, The Netherlands, England (UK), Scotland (UK) and Wales (UK).
The maps do not represent the official view or position of the countries.
Distribution maps of native mosquitoes
The maps show the current distribution of native mosquito species in Europe at ‘regional’ administrative unit level. The maps are based only on confirmed data (published and unpublished) provided and validated by experts.
For native species, the possible distribution statuses are:
- Present: The species has been observed to be present in at least one municipality within the administrative unit.
- Introduced: The species has been introduced in the administrative unit without confirmed establishment.
- Observed Absent: Field surveys or studies on mosquitoes were conducted but the species has not been detected within the administrative unit.
- Anticipated Absent: These are administrative units where there are no data, and where the species is anticipated to be absent, based on a distance of at least 100 km from units with observations, and unsuitable climatic conditions.
- Unknown: Data from the administrative unit may be available but there are doubts about the identification and/or the status.
- No Data: No sampling has been performed and no data on the species are available within the administrative unit.
Vector distribution status changes in terms of spatial units since the previous update
In this update, the current known distribution of the 14 priority native mosquito species resulted in a total of 777 new administrative units with presence, with most new information in Greece (162 new unit/species presences), Sweden (131) and Türkiye (88).

Surveillance for native mosquitoes
The surveillance maps shows the regions where surveillance activities for native mosquitoes were held in Europe and neighbouring regions.
The map 'Seasonal active surveillance for native mosquitoes over 2017–2019' shows the number of different calendar months in which any active surveillance took place per administrative area.
The map 'Invasive mosquito surveillance effort over 2015–2019' shows the surveillance effort per administrative area, by highest surveillance type.
