Osmia (Melanosmia) virga Sandhouse 1939

County records: Allegan, Berrien, Clinton, Crawford, Muskegon, Osceola, Ottawa, Van Buren.

Notes. A potentially valuable native pollinator of blueberry due to its preference for Vaccinium . Mitchell (1962) recognized only the male, contributing to this species being overlooked or confused with O. felti (see Giles & Ascher 2006; Goldstein & Ascher 2016).
