Hawthorn Moth?

This pretty little thing was spotted out on the walk with Elvis. I’ve tried to identify it, but not sure I have succeeded. The butterfly id sites don’t have anything really close enough. The only close-ish thing is the Hawthorn Moth. It feeds on hawthorn (who would have guessed!) and other similar plants, such as blackthorn. It was near a series of blackthorn bushes. Anyone any ideas?
