I have grey banded solitary bees every year they nest ( well not nest) but build their egg safe, mud sealed, incubators in any large empty screw hole. Their favorite is my wall mounted hose reel. For 10 years now we have had their company. They buzz me when I roll out the hose but never a serious threat, in fact, last couple of years they just ignore me.
We also have leaf cutter bees(similar in appearance) who love chopping up my mandarin and lemon leaves for their larvae to feast upon.
No honey…but such nice creatures.
