I do not see a proboscis, which I think eliminates it from being an Orchid bee. The Sweat bee pics I have seen all seem to show them with much more "fur" on their abdomens than this one. As well as having stripes. This one does not appear to have any of those. I have two more pics of it to share, but Lemmy (website) is being unkind at the moment, so I will try to find a work around to be able to upload the other two.
I would have thought an orchid bee as well
