Osmia (Osmia) cornifrons (Radoszkowski, 1887)

Comments: This non-native species was intentionally introduced into the United States, with introduction to the East Coast occurring in 1977 (Batra 1979). This species has spread westward, and although it has not been detected in Minnesota, it has been found in Wisconsin (Madison and vicinity) and Iowa (see https://www.inaturalist.org/ observations?place_id=1&subview=map&taxon_id=121508), and we expect it to reach MN in the near future.
