That’s my best guess. Can’t find much on size or range, but this guy seems a bit big (about honeybee size) for that species. Also, don’t know if he’s supposed to be here.

Based on images posted to BugGuide, this could well be Diadasia enavata, but we cannot be certain. We will post your letter and photos and perhaps someone with more knowledge of Solitary Bees will be able to assist in a species identification or confirmation. Your photos are quite nice.
