Beheaded Fox Moth

Something beheaded this Fox Moth found on the moor yesterday.

I've realised that the small day flying "moths" from last weekend were Dingy Skipper (not a moth). This is not a species I am familiar with. I found two on the heather behind the house in the sun last weekend and in the hope of getting an ID didn't look at them but attempted and failed at photoing them :-( Fortunately the Lewington book has sorted me out as I remembered enough to eliminate the confusion species of day flying moths (unless there are others not included there).
