Can anyone tell me the id of this if my little orchid is helpable

That looks like the juvenile stage of boisduval scale. Spray the entire plant and medium surface right away with 70% alcohol (rubbing alcohol.) It may be on your other plants, too. You will need to be vigilant but if you treat right away you can get it under control. Do some more reading about this bug.

Thanks Es. I have to admit though you give me quite a spook. I did jump in and I had to use a-tip swabs,just for tonight cause all I had on hand was 91% is.alco. So I just swabbed the main ones off with that for now and tomorrow I’ll head to the store and get some 70% to spray all my orchids. The store is about twenty five miles away😔
Thanks much.

Thanks much.

Or just dilute some of your 91% ...If you put 8 parts 91% alcohol with 2 parts water you're be close enough. (Does't have to be exact) And save both time and gasoline.

I’ll try that, thanks Roberta!

It looks to me like Es hit it right on the head, continueing pics on another plant ,my recently purched dendrobium,and it came to me with some of this damage already. I also dont think it brought it all to me as the first pic at the start of the thread,I had a while. So it has been from several sourses appairently. Heres some pics .

The scale isn't eating those holes. Something else is.

Slugs? They are voracious. And sneaky.

[Waterdog111]

If you expand it and look closely at the last pic, can you tell me what those tiny white spects and if the pic was more clear you could see on the sides of two are very tiny brown spects as part of them.
Im not saying I dont have slugs but the only thing Ive seen close to them are a lot of the small snails(I do have a goodly supply.of them)
Thanks for the help. I think the alcohol helped my oncidium, the two leaves that were mostly yellow are more green now after only 24hrs.

The tiny bush snails are mostly destructive of roots. Snail baits don't faze them. Search the Board for "coffee" to find some good advice on handling them. But they aren't responsible for the big bites, they are too small (They can attack the surface of leaves, but that's about it, they're rather eat the roots). Slugs, full-size snails, and caterpillars can take the big bites. The caterpillars often go elsewhere after they have munched. The full-size mollusks usually stick around, but hide until after dark.
