I can only find images of the younger, brown stage of Large Emerald in my books and on-line, but the shape and posture of this one match very well. My books state they turn green after hibernation - which no doubt improves their camouflage against the new leaves. Birch is also noted to be the main foodplant which is another good pointer. Well spotted!
Thanks, Vinny. There is a dearth of pictures of the larva on the web, but I guess you are close if not right on the button.

Various stages of Large Emerald are shown on Reg Fry's site:
The colours shown there are a bit different to yours, but the shape is a perfect match, and I think Vinny has the correct ID for this one.

Thanks, both. I have been away for a couple of weeks, hence the delay in responding.
