White objects on Onc Isthmi

[JeffreyR]

I have a newish (2-3 weeks) onc isthmi growing in moss in a clay pot. It is a well established large plant with perhaps a dozen bulbs, 2 of which are old and have no leaves.

It has outgrown the pot (overflowing) and I will repot after blooming. In the meantime, I’ve put the small pot in a bigger pot and recently (1 week) added bag of Better Gro orchid moss. I did not do anything to treat or sterilize the moss. Just rehydrated it.

On an evening check of the plants, I noticed a few white objects (eggs?) on the underside of one leaf. I’m 90+% sure they were not there before.

I’m attaching photos.

They are very tiny, 3D, and in a row. One row of 2 and one row of 3.

Can anyone identify the items? Recommend a treatment? Suggest where they came from - the plant already had them or they came in with the moss?

And now it is 2 and 2. One has crawled off or fallen off.

I have the 409/alcohol mix handy and have used it for mites on a new plant with success in the past. It is my go-to when I suspect a problem and so far have avoided any real infestations.

Thanks in advance,
