The burnished brass, Diachhrysia chrysitis, is a moth found ‘almost everywhere’ but typically in gardens and in hedges and on rough ground. One of its foodplants is nettle, so it should feel at home in our garden.
I’d describe its background colour as pale straw with perhaps the slightest tint of lime.
The front of the head is ginger in contrast to the mottled brown of its other markings. By breaking up the colour like this and breaking up its shape with tufts and a small cockscomb this moth could pass itself off as a broken off piece of plant debris.
Playing dead, as it helpfully remained while I drew this, it would be perfectly disguised amongst summer leaf litter.

Any Suggestions?

But having said that it could in fact be the architypical little grey moth, the imaginatively named grey.
