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.
