Red Admiral I wonder?

Oddly, I think I would recognise a red admiral.
Could have been one of these:

Very pretty but not a butterfly of course.

Hmm, sings are in the wrong direction.
Not sure it's the same one, as I remember checking the one I saw and I'm
pretty sure it /was/ a butterfly not a moth, and there is less red on the
one in the picture. It's the 'right' red though.
