Can anyone help me identify these pests?

I got a beautiful white orchid about a month and a half ago and within the first week all the flowers had fallen off. No big deal, the plant still appeared healthy so I followed advice found on the Internet to cut the stem above the first knot or future bulb and continued to feed and water it and give to plenty of sun. The leaves still appear bright green and healthy, but now the stem has turned dark at the top and is yellowing all the way down toward the base of the plant. I've also observed tiny light brown bugs at the top of the stem, but they crawled back into the stem before I could get a good photo. Can anyone help me?

Don't know what bugs but cut the entire flower stem off to the base, like now! LOL
It will sprout another one probably in a few months.

When your info referred to "cutting above the first node" it was referring to the first node from the bottom of the blooming stem, not from the top. I agree with flexd in cutting it to the base at this time, being sure not to cut into the leaves.

I suspect these may be fungus gnats and not a huge problem, but may indicate a change in potting medium is due. Check the "The Phal abuse Stops Here" sticky at the top of the Beginner Forum for lots of Phal info.

Good luck and welcome to the OB.

Welcome to the Orchid Board! We look forward to visiting with you. There are a lot of friendly people here. When you get a chance, introduce yourself:

The plant is a Phalaenopsis. You can read how to take care of them here:

Phalaenopsis care

The flower spike dies back after it blooms, so you can safely cut it near the base of the plant. If you take good care of the plant, it will make more bloom spikes in the future. As it grows bigger and bigger, it makes more and more flowers.

They are probably something related to springtail, although springtails are silvery in appearance.

The brown ones, I don't know the name but if that's what I think it is, basically look the same and act the same way.
They are slender and quite small, and very fast moving.

I think they eat the decaying organic matter in the pot and not a threat to the plants.

If that bothers you, you can repot the plant.
Get rid of the old mix, and wash the roots gently.
If you don't wash the roots, they will be back very soon.

I don't know how else to get rid of them.
I think I have many of them, but I just let them. only squeeze them to death with my finger when I feel like it. lol
