I'm stepping outside my area of competence (?) here but I wonder if this is a female hairy footed flower bee. I see them in my garden occasionally - they're quite common. Can you put in on its side and take another photo? Anyway, see -
I agree with jaguarondi - a female Anthophora plumipes, Hairy-footed Flower bee. They are just about at the end of their season now so no surprise to see a few sitting the wrong side of the perch. The good news is she will almost certainly have completed her construction and provisioning of her brood cells, each one ocupied by a single larva, that are presently munching their way through the pollen she’s has industriously collected for them. This cohort will be adult by the end of the year but will not emerge until next March/April.
