That's what it was in this case, although the victim has been well-preserved in all his or her delicate beauty. What is it? I do not know but am about to enquire of the experts on the Upper Thames Moths blog. it's perhaps a bit supine not to have a guess, though, and mine would be Crambus perlella, because of the long palps. Second choice, Elachista argentella. Both are summer moths but I've no idea when it died.
Out of doors has at last gone icy and frosty, as it ought to do in winter, and both I and the trap are having a well-earned break.
