MosquitoLUX – Atlas of the mosquitoes of Luxembourg


Culex modestus, first detected in June 2019 in Remerschen.

The project MosquitoLUX (2019-2022) aims to compile and complete knowledge on mosquitoes (Diptera: Culicidae) in Luxembourg. In a context of climate and environmental change, this first mosquito atlas should make it possible to draw up an inventory of Culicidae fauna, in terms of biodiversity first, but also in terms of public health and vector risks. The latter requires not only the collection of presence/absence data, but also abundance and seasonality according to different environments. This inventory should also make it possible to detect introduced invasive alien species and changes in the distribution areas of native species.
