Summary

In the UK, there are 36 mosquito species. Of these, a handful of species are associated with nuisance biting reports, and a few species have been implicated as vectors for disease transmission in other countries, including West Nile Virus, and Usutu. Therefore, it is important for us to have an understanding of their distribution across the UK.

As a result of changes in climate, the distribution of our native species, along with their seasonality, may change, with species previously thought to occupy only the warmest regions, being found in more northerly areas. Many native species will exploit summer flooding, therefore, changes in rainfall may impact the distribution and seasonality of species, potentially opening up new locations for them to exploit.

UKHSA Medical Entomology run surveillance and research projects for native mosquitoes. More information can be found under the Monitoring and Surveillance section.
