Osmia bella Cresson, 1878


Scientific Name: Osmia bella Cresson, 1878

Common Name: Osmia bella


Osmia bella Cresson, 1878 : 107 [♂].

     Lectotype , designated by Cresson (1916: ). USA, Colorado, by Morrison [ANSP no. 2554].


Taxonomic notes: Michener 1936: 17) listed O. bella Cresson, 1878 as the ♂ of O. cobaltina Cresson, 1878 which was subsequently supported by Sandhouse (1939: 134) [in part], and by Michener (1951: 1168) and Hurd (1979: 2042). Interestingly, Sandhouse (1939: 133) also listed O. bella as a synonym of O. bruneri Cockerell, 1897 [in part], though presumably this was based on examination of Cresson’s paralectotypes, as O. bella would have priority over O. bruneri. All three are now considered valid species, so the ♀ of O. bella has not been described, but is known (e.g., Howell and Alarcón, 2007, visitor of Penstemon flowers). Cane et al. (2007) also indicated that O. bella was routinely collected on flowers in the Cache Valle of Utah, though the species has never been recorded from trap nesting programs, suggesting that it may not nest in pre-existing cavities.

DNA Barcode Index Number (BIN): BOLD:AAF2159, BOLD:AAF2158

BIN BOLD:AAF2158 is represented by a single ♂ specimen from Utah, while members of BIN BOLD:AAF2159 include ♂ and ♀ from British Columbia, Oregon, California, Utah; one of the specimens from the latter location is identifed as O. cobaltina.

Distribution in Canada: Sheffield and Heron 2019 [BC].
