This moth (or butterfly?)was found lying on the ground on a stone slab, outside our kitchen door, and actually scared my partner who first saw it! as it has a strikingly real "face" as shown on the attached picture. I have seen butterflies with "eyes" before but nothing quite like this before. Could you please identify it for me? It measured approx 60-65mm across. We live in the Aeron valley, in Ceredigion, Wales, which has a river nearby and is mainly farmland & woodland.
