Lasioglossum (Sphecodogastra) oenotherae (Stevens 1920) (lusorium group)

County records: Ingham, Kent, Livingston, Washtenaw.

Notes. The nesting biology of Ontario populations have been studied in detail ( Knerer & Mackay 1969). Records of this species are largely absent from the Midwest, although the species occurs widely from the Central Plains to Maritime Canada ( Gibbs et al. 2013; McGinley 2003). Multiple attempts by JG were made to capture female L. oenotherae in Ingham County from Oenothera spp. ( Onagraceae ) in the early and late hours of the day without success, but two males were obtained from other flowers during the middle of the day when females would not typically be active ( McGinley 2003).
