Butterfly on the buddleia

I love being home for blips, there's always plenty in the garden to use. I went round the garden collecting a few bits to put in a vase on the dinner table and when I got to the Buddleia there was a bee on the first flower, a wasp on the second and this beauty on a third.

The creatures LOVE that plant.

And when it's in flower, which is a good amount of time, it really is a lovely sight.

I think it's a Red Admiral butterfly?
