Aim: Anthropogenic landscape change, such as urbanization, can affect community structure and ecological interactions. Furthermore, changes in ambient temperature and resource availability due to urbanization may affect migratory and non- migratory species differently. However, the response of migratory species to urbanization is poorly investigated, and knowledge for invertebrates in particular is lacking. Our aim was to investigate whether there was a shift in community structure and phenology of hoverflies in urban landscapes, depending on migratory status. Location: Switzerland. Methods: Using a paired design, we compared urban and rural landscapes to investi-gate the impact of urbanization on the abundance, diversity and phenology of hover-flies. Furthermore, we tested whether migratory and non- migratory species responded differently to urbanization. Results: We observed a difference in the response of migratory and non- migratory hoverfly communities. Although the abundance of hoverflies was higher in the rural ecosystem, driven by a high abundance of migratory species, there was no difference in species richness between the land use types. However, the community structure of non- migratory species was significantly different between urban and rural ecosys-tems. The phenology of hoverflies differed between the two ecosystems, with an earlier appearance in the year of migratory species in urban landscapes. Main conclusions: To our knowledge, this is the first study to investigate the re-sponse of migratory insect communities to urbanization. We demonstrated that mi-gratory and non- migratory hoverflies respond differently to urbanization. This highlights the importance of differentiating between trait and mobility groups to un-derstand community assemblage patterns in anthropogenic landscapes. The differ-ences in phenology supports the growing evidence that urbanization not only affects the phenology of vegetation, but also affects the higher trophic levels. Changes in the phenology and community composition of species as a result of anthropogenic landscape change may have important implications for the maintenance of key eco-system functions, such as pollination.
