Its evolution may well come down to resembling a flake of wood, but it's the curious refinements which fascinate me. That black-topped mohican half way along its body, for instance. How has that helped the PP's fitness to survive?
Survive it does, a common moth if seldom seen by most of us, with thriving colonies as far north as Scotland's Great Glen. I am going to be in the latter in a few weeks' time but, alas, there won't be room in my suitcase for the moth trap.
