Ashy Mining Bee

Never seen one of these before. There's a beautiful bush in our front garden that is covered in white flowers. I spotted about 6 different species of bee enjoying it as I walked past but this one caught my eye as it was a little more shy than the rest. Took a (slightly out of focus) picture and managed to identify it. Can't tell if this is the male or female. Still, always nice to see a friendly bee doing well.
