Shiny backed bee

Shiny backed bee

Observation - Shiny backed bee - UK and Ireland. Description: I have no idea what this could be, as it doesn't resemble any of the pictures I've found online. I didn't see it with open wings so am not sure what colour the abdomen is. The thorax seemed shiny rather than very hairy.
