Possibly a September Thorn moth.
Below: a variety of common lizards basking at Llanymynech Rocks this morning.
So much of wildlife-watching is waiting, and often failing to see what you went to look for. But today began with two new-to-me species of moth, a Bulrush Wainscot and a Common Wainscot, plus this characterful Thorn. Mid-morning a trip to Llanymynech Rocks revealed a dozen or so lizards happy to pose while I photographed them. I was very taken with the variety of colours they come in. The air was full of butterflies, especially Common Blues and Small Coppers. Then this evening, a water vole, very close and bold (until I moved!).
Some days are magical.
