Butterfly In Disguise

I was going to post a picture of a peony today the first flower of which has just opened up in our garden but then I spotted this creature on a wall about a quarter of a mile from home.

A quick Google for "camouflaged moth" brought up many similar images which lead me to believe it's a Pandora Sphinx Moth BUT as this is a North American moth I'm not absolutely certain that it would be seen in the UK so my identification may not be correct. It's certainly one that I've never knowingly seen before in these parts which is why I've titled this post "Butterfly in Disguise". So calling all lepidopterists out there, is my identification correct or not?

Peacock

I suppose subconsciously we've been looking for signs of spring for a number of weeks but now the daffodils are flowering, blossom is forming on the trees and the sight of a peacock butterfly basking in the warm sunshine today is proof positive of the season.

The name for this species of butterfly, owes its origin to bird of the same name and is because of the similarity between the eye patterns on the wings and those on the tail feathers of the bird.
