Notes on the nesting biology of two ground-nesting species are provided from Central Michigan. A single nest of Augochloropsis metallica fulgida was excavated on 12 July 2014 in Shiawassee County. There were two female nest inhabitants. Examination of mandibular wear, wing wear and ovarial development suggests one female was acting as a worker caste. Also, a nesting aggregation of Megachile mucida was observed in Ingham County. Information on nest architecture and cell construction is based on excavations of several nests during 7–15 June 2014. Megachile mucida is recorded as a new host species for the cleptoparasite Coelioxys sodalis. This is the first record of M. mucida in Michigan, additional collection records of this species in Michigan are also reported.
