This washed out dropping was found on a moorland tussock 1 foot from a regular fox dropping with a pointed end, which contained sheeps wool.

It contains many large beetles. I think the 2nd crop shows a Dor beetle limb. It was found 20 yards from what I think is an otter holt entrance, not far from a small lake which contains trout. Can anyone suggest which species is likely to eat so many beetles?
