Epeolus interruptus Robertson 1900

County records: Cheboygan, Kalamazoo, Lake, Livingston, Midland.

Note. A possible cleptoparasite of Colletes aestivalis Patton according to Brumley (1965), but this host is very rare in Michigan (and elsewhere) with no recent records from the state suggesting that an associated parasite would be of conservation concern.
