Diptera species taxonomy and behavior

In this study we present a commented and referenced species list of the Syrphidae (Diptera) collected during the surveys of the Our Planet Reviewed in Corsica 2019-2021 programme. We studied a total of 2420 specimens belonging to 131 taxa, which were collected during the field campaigns between 2019 and 2022 using different methodologies: hand collecting, hand-net, interception traps, light traps, Malaise traps, sweep-netting, and coloured pan traps. The genera Anasimyia Schiner, 1864, Brachyopa Meigen, 1822, Lapposyrphus Dušek & Láska, 1967, Lejops Rondani, 1857, Melangyna Verrall, 1901, Neocnemodon Goffe, 1944, and Parhelophilus Girschner, 1897, are recorded from Corsica for the first time, and we also provide records for 30 species new to Corsica. Among the studied material, we present records for 17 threatened species in Europe and three endemics of Corsica. Furthermore, we report a new location for the Critically Endangered Riponnensia daccordii (Claussen, 1991) and corroborate that it is not extinct.
