Unknown little insect in new orchids...

[musicloveranthony]

I recently purchased 4 plants from ebay (won't be doing that again, unless I know the vendor). One is a really large Paph Prime Child (10+ growths), another is a 4 growth Paph Oberhausen's Diamant. They're both plants I'd been really looking forward to. Imagine my horror at finding they had pests. The Prime Child has at least got orchid snails, if not more.

My question is about what I've found in the Oberhausen's Diamant. I repotted the plant into a clear pot and while watering, I noticed several tiny, extremely fast moving little bugs. They are really tiny, about the size of this slur ~

I left the plant alone to make sure I wasn't hallucinating. When I came back I couldn't see them, until I moved a lower leaf. Out scurried two of the bugs. They really do move FAST. I have no idea at all what they are. They are either silver, or a silvery white. I know they're not fungus gnats, or spider mites, or slugs, or scale insects. I tried doing an immersion in a soap/oil bath, but it didn't kill them.

Again, these are plants I was really looking forward to, but I can't risk the health of my other orchids...I'm at a loss.

Any help would be much appreciated
