Hibernating Moth
I think this is a Scalloped Hook-tip moth, there were a few of them sheltering in an old derelict slate mine.
This species has an unusual resting posture, with the wings held in an arch over the back, resembling a dried leaf. It is mainly a woodland species, and feeds as a larva on birch (Betula). Double-brooded, the adults can be found on the wing in May and June, then again in August.
It is reasonably common over much of Britain in suitable habitat.
