Biting midge maps
The biting midge maps are published regularly to provide the EFSA and ECDC stakeholders, the scientific community and the general public with updated information on Culicoides distribution at ‘regional’ administrative unit level (NUTS3 or equivalent and NUTS2 in Austria, Belgium, Denmark, Germany, The Netherlands, England (UK), Scotland (UK) and Wales (UK)). Please note that the maps do not represent the official view or position of the countries.
Surveillance for biting midges
The surveillance maps shows the regions where surveillance activities for biting midges were held in Europe and neighbouring regions.

Distribution maps of biting midges
The map shows the current known distribution of several biting midge species in Europe at ‘regional’ administrative level (NUTS3). It is based on published historical data and confirmed data 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: Culicoides chiopterus, Culicoides dewulfi, Culicoides imicola, Culicoides kingi, Culicoides newsteadi s.l., Culicoides obsoletus/scoticus, Culicoides pulicaris/lupicaris and Culicoides punctatus s.l.
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.
- Anticipated Absent: the species has never been reported and there is a high probability that it is absent.
- Confirmed Absent: the species has never been reported within the administrative unit and there have been field surveys or studies on biting midges within the last 5 years of the distribution status date.
- No Data: No sampling has been performed and no data on the species is available.
- Unknown: The status is unknown
Areas outside the scope of the VectorNet geographical scope are colour-coded as ‘Outside scope’.
Vector distribution status changes in terms of spatial units since the previous update
Since the previous update (October 2020), a limited number of recent references providing distribution data on Culicoides was captured, relating to 19 locations in 12 different NUTS3 from 5 countries (Greece, Italy, Spain, Turkey and United-Kingdom).
References provided mainly presence data, with the exception of a seasonal (July to October 2018) dataset from Spain. All data were located in NUTS3 for which distribution information is already known, with the exception of a dataset on 1 NUTS3 in Turkey for Culicoides imicola and Culicoides obsoletus s.l./Culicoides scoticus, but also Culicoides circumscriptus, Culicoides gejgelensis, Culicoides longipennis, Culicoides maritimus, and Culicoides subfasciipennis. This is the first distribution data for this country.
Culicoides obsoletus/scoticus - current known distribution: March 2021
Culicoides punctatus s.l. - current known distribution: March 2021
Culicoides chiopterus - current known distribution: March 2021
Culicoides imicola - current known distribution: March 2021
Culicoides newsteadi s.l. - current known distribution: March 2021
Culicoides pulicaris/lupicaris - current known distribution: March 2021
Culicoides dewulfi - current known distribution: March 2021
