Treatment

= Andrena (Trachandrena) compacta Mitchell, 1960: 181 (Michigan holotype; Fig 7A View FIGURE 7 ).

Holotype. ♂ USA: Michigan: Roscommon Co.: 26 May 1957, R. & K. Dreisbach ( NMNH: 75174). Synonymy by LaBerge (1973).

County records: Allegan, Antrim, Arenac, Clare, Crawford, Emmet, Grand Traverse, Gratiot, Houghton, Ionia, Iosco, Iron, Kalamazoo, Kalkaska, Lake, Livingston, Mecosta, Midland, Missaukee, Montcalm, Monroe, Montmorency, Muskegon, Newaygo, Oakland, Osceola, Oscoda, Otsego, Ottawa, Presque Isle, Roscommon, Saginaw, Shiawassee, St. Joseph, Van Buren, Wayne, Wexford.

Notes. LaBerge (1973) records A. ceanothi as a polylectic species, although it was reported as a Vaccinium specialist by Goldstein & Ascher (2016) in an analysis lumping oligoleges and mesoleges. Nearly half its flower records are from Rubus ( Rosaceae ), but it does also show some preference for Vaccinium and may prove to be a valuable wild pollinator of berry crops.
