Do you know what this very small black bug is?

[lotis146]

Aw geez, trying here as well as pests because I am unable to identify this creature that just showed up. I found it on a Tolumnia Buck Hollow I just received Saturday. It's shiny & sort of beetle like. Before spraying again in afternoon I saw a bunch of them crawling on the roots and up the sides of the pot. Then when I spray with water they disappear.

The Tolumnia lucayana I just got today had very, very small greyish bugs crawling on the upper lip of the outside of the clay pot. They were much smaller and rounder than the springtails I just had on a Phal. I assume mites.

So I went to Lowes & got Bayer Advanced Nutria. It says it kills mites, spider mites, aphids, scale, mealies, and more, also a Fungicide. I wanted to go harder but it was late in the day and I can't risk bringing them back inside after spraying and an odor still being apparent given my parrots. I'll toss them before I do that.

That said, I sprayed them good (very small plants) outside while 58 F and left for hour or so til 52 F. Brought them in. Checked a couple hours later & no OBVIOUS signs of the mites (they were so small, I only saw them because they were crawling quickly right after I watered it). BUT BUT BUT the little black bugs? Yeah they're there just not as many but then I see that now they're on the micro-mini Tolu. lucayana when they weren't before!! Almost like they took off from the spray!

In the last week I got Wils. Peach Cobbler, Zygo. Rhein Moonlight, Paph Hawaiian Illusion, a free Phal. Yellow Brite Lites, & the two Tolumnias. They're all from different sellers except Wils. & Phal. I've kept them all in the same room, not touching each other but all within 3-4 feet. I don't know if these guys fly, they aren't apparent on the Wils. or Phal. that I got Saturday before Tolu. Buck Hollow on Monday. Everyone else arrived today. The seller doesn't know what they are and suggests I use a dish detergent mix before I said I spray Natria. I feel discouraged they're still traveling.

Here's a picture I found online someone else posted but they look like what I'm dealing with
