Elephant Hawk Moth Pupa -Female

Found this chrysalis poking out of the very wet muddy path, where it was likely to be trampled. It was squirming and moving and appears to be fine, but we'd sure like to know what it is going to be.

Update: Thanks a million to the folks over at Back Garden Moths for the ID on this and especially to The Lepidopterist for all the helpful information as well as the ID.

This is one of the most beautiful moths we have in the UK, for some examples of them click here
