Megachile (Megachile) lapponica Thomson 1872 (New state record)

County records: Keweenaw.

Notes. This record comes from a specimen identified by S. Droege. Due to a paucity of records of this boreal species from the Eastern United States and its similarity to M. relativa , additional collections and molecular confirmation would be desirable. North American populations of this bee were called M. nivalis Friese until Sheffield et al. (2011) placed this in synonymy with M. lapponica , described from Sweden and now considered a naturally Holarctic species.

Nests in logs in Saskatchewan ( Peck & Bolton 1946).

Specimen record: Keweenaw Co.: Isle Royale , Davidson Island, N48.1252, W88.5111, 4 Aug. 2013, S. Wilson (1 ♀ PWRC).
