It's a bee. There are lots of flies (and other insects) that mimic bees. Most bee-mimicking flies still have very short antennae that characterize most flies. But this has long antennae, elbowed near the base. There are various other details that also say "bee".
I can't be sure of a further ID here, as there are several bee families that look like this and are rather hard to tell apart except thru details that are not visible here.
Thank you very much Mark, AGAIN, for your invaluable knowledge in these matters.
