Epeolus ainsliei Crawford 1932 (New state record)

County records: Livingston.

Notes. Possibly a cleptoparasite of Colletes susannae Swenk. The two were recently collected together in relative abundance in Birds Hill Provincial Park, Manitoba, and have been found together in the past (Wolf & Ascher 2009). However, Colletes susannae is not known to occur in Michigan and the host plant of this bee, Dalea purpurea Vent., is rare and possibly adventive in the state (Voss & Reznicek 2012). Colletes americanus Cresson has also been collected in association with E. ainsliei (Wolf & Ascher 2009) . The closest previous record of the prairie-associated E. ainsliei was from Wisconsin (Wolf & Ascher 2009).

Material examined. Livingston Co.: E. S. George Reserve, 19 Jul. 1960, F.C. Evans (1 ♀ UMMZ) , 2 Aug. 1960, U.N. Lanham (3♀ UMMZ).
