Check out the various 'thorns'; it might be purple thorn, Selenia tetralunaria; it is a bit tricky to tell from the funny angle in your photo.
Your 'moth' is a Lilac Beauty (Apeira syringaria), they have an odd fold in the wings which makes them look as if part of the wing is rolled. One I've never had the pleasure to meet yet, so congrats
Thanks guys, never seen anything like it.
My little boy, Jack aged 9, discovered it on the fridge, he's the nature expert in the house. He's now also a big fan of Nature Plus!
We let it fly away straight after the photo was taken.
Thanks for letting us know you let it go.
It is one of the things that perpetuates the mystery for me - how moths appear from the huge black emptiness of the night, and then disappear from whence they came - denizens of another realm. That they choose to grace us with their myriad fascinating patterns, for no benefit to themselves, and for our delight, is a wonder - for those with eyes opened by curiosity.
