Their presence was previously confirmed in Michigan, Ohio and Pennsylvania. “Although we do not know the extent of the impact of nonnative bee species, there is evidence they may compete strongly with native bees for nesting resources.”
(USDA ARS) Exotic Bee ID, a website created to help identify non-native bees in the United States, has been expanded to include more information and species.
