Data from: Think globally, breed locally: Limited genetic impact of management in solitary bees (Osmia cornuta and Osmia bicornis)

This dataset contains multilocus genotype data for two solitary bee species, Osmia cornuta and Osmia bicornis, generated using 11 microsatellite markers. All specimens were collected in Switzerland and include both contemporary samples collected in 2023 and historical specimens collected between 1990 and 2000 from Swiss entomological collections. For a subset of individuals, the dataset also reports the NCBI accession numbers of mitochondrial DNA sequences (COI region) generated as part of this study. These data enable comparisons of genetic variation and population structure between O. cornuta and O. bicornis, as well as between historical and contemporary populations, using a common set of neutral genetic markers.
