who are they?

They're not hurting the orchids at all, not leaves, not roots, so I'm happy to let them stay. I think they eat the algae, and I'm ok with that. Like orchideya's, mine are pretty active as well, and they jump incredible distances for their size. Orchideya, do yours jump?

If these are predatory mites, does this mean they eat other pests?

Mine don't jump, just run around. I think mine are similar in size to yours, if you mean the small dark dots on the back wall of the pot, but they are cream-beige colored.

I don't see any damage to orchids either, they just freak me out by moving there.

I have ordered some large bark from Agrogreen Canada and will replace medium in all my shultz potted phals.
