I agree it is one of the psychids, not sure which though, e.g. Luffia ferchaultella might be possible as well? Doesn't look quite angular enough for Narycia, but I'm not certain.

Which Psychidae?

Thanks Martin, glad to hear you agree with Psychidae. They could well be Luffia ferchaultella - another lichen muncher - based on pics I've now found. I'm no expert on this family, but knew they couldn't be Tineidae (which I'm sadly far too familiar with thanks to wool carpets and cats...) and guessed it was a bagworm. Narycia duplicella seemed a pretty good match, but closer pics might be needed or ideally the moths hatched from pupae!
