Ruby Tiger Moth

We were staying in Glen Trool with friends for the weekend. Friday evening was spent looking at stars, taking advantage of Galloway's dark skies. Saturday dawned bright and cool and there were a number of moths warming in the sun. I took some shots from above and also from the side, that were crisper than this one. However, I chose this for the blip, as it shows the underside of the moth through a window. I believe it is a Ruby Tiger Moth but if anyone knows better then please let me know.
