Notes. The nesting biology of M. brevis in Kansas has been studied in detail (Michener 1953). Additional studies of this cavity and stem-nester are available from Kansas (Baker et al. 1985), Missouri (Rau 1934), Wisconsin (Medler & Lussenhop 1968), and Oregon (Rockwood 1951). The latter may pertain to M. onobrychidis Cockerell, which was formerly considered a subspecies of M. brevis (see Sheffield et al. 2011; Bzdyk 2012).
