Please read my revised initial post. Follow Sdaji's advice. Although I feel pretty stupid and sheepish about it, in this this instance it is a good thing to wrong in my initial take on it. Mite are smaller, round (not angular or elongated) and mostly lodge underneath scales and around the eye. If they were sitting on top of scales, especially in those numbers, you see them moving. Once again, I do apologise for the misdirection.
