So the hope of positive bee ID looks like it has buzzed off, but on the up side a hoverfly I photographed yesterday has been identified as Cheilosia grossa (thanks to the guys on UK Hoverflies facebook page!). I briefly tried to look for it in my hoverflies books last night, but now I can drill down on it I'll get a better idea of what to look for next time around. I also just realised that since the bee failed, this is the actual 200th species for Cullalloe this year! AND it's a new record for the reserve into the bargain. Hoorah!
