One of four specimens collected on Phacelia distans.
Will post a specimen photo separately since I'm not sure which of the four specimens corresponds to the present photo, just certain I caught this one right after taking the photo.
Keyed specimens using Michener, et al. (1994). The Bee genera of North and Central America. Please see also notes with specimen photo posted separately.
