Need help identifying some bugs!

[Jlin]

Hi everyone,
I received a Cuitlauzina pendula last fall. It wasn’t in the best condition and I had to remove all the roots. After several months, it now grows really well, has nice plump Pseudobulbs and has a nice flower spike coming on at the moment.

I started noticing a few black, round bugs with long „horns“ crawling on the plant when I watered it under the sink. I saw some maybe eating some happy sap (not sure though) but otherwise they seem to live in the media. I don’t see any damage on the plant and given the look of the pseudobulbs and the fact that it doesn’t wiggle in the pot anymore, I don’t think they eat the roots. Any idea what those are?

Last time I watered I also saw some pests that look like thrips to me (Long and silvery), in addition to the other round bugs. I noticed these in the media of other plants too but can’t see any damage, or the bugs on the top parts of the plants. Could they be detritivorous thrips?

Thank you all!
