A greyer shade of grey
How many times have I sighed about small and brown or boringly grey moths which I have such trouble sorting out? Oh well. Their colouring doesn't come without good reason. You would have to be a very keen-sighted bird to spot the Clouded Drab on the stone above. It's coincidence, but if you click on the pic to enlarge it, you'll see that parts of the wing pattern and the slightly pitted surface of the rock are almost exactly the same.
I thought initially that this was a Lead-coloured Drab, a slightly rarer relative of the Clouded. Catchy names, eh; a bit like the Grundies in The Archers. I sent my photo to Charlie Fletcher, the Yorkshire county moth recorder, and he opts for Clouded; not on wing pattern or colouring which can be more or less identical (the Clouded Drab is infuriatingly varied), but because the Lead-coloured Drab has more feathery antennae (or bipectinate if you are being posh, says Charlie). So in his excellent comparison picture below, it's the one on the right.
