Recent records of Mesembrius peregrinus (Diptera: Syrphidae) from the Czech Republic

Abstract: The hover fly Mesembrius peregrinus (Loew, 1846) is the only European member of the genus Mesembrius Rondani, 1857. This species seems to be rather thermophilic in the Czech Republic and it mainly inhabits reed beds and margins of lakes and ponds with well-developed littoral vegetation. In the Czech Republic, there are only very few historical records of M. peregrinus and only a single locality with recent records of M. peregrinus (south Moravia, Lednice). The species is therefore considered as a critically endangered species in the national red list. Here, we present further recent faunistic records of the species from three additional localities in Moravia, Czech Republic. The ecology and overall distribution of the species are briefly discussed.
