Fungus Gnats??

Looks like flying aphids to me Keep an eye on the underside of leaves

The photo isnt clear enough to say one way or the other but if you have bugs in the soil you can top dress with diatonaceous earth (dont put too much) and it rips their tiny bug bodies open and they die of dehydration and shoukd clesr up in a few days. Nematodes SF work at clearing out the larvae in the soil, you just water a tiny bit of the egg powder in and give it a couple of days. In the mean time, get yellow stickies from garden center cause they will help until DE / nems do their thing. Otherwise, if you are not obsessed with microbial life you can water with a hydrogen peroxide (H2O2) dilution which is supposed to clear them out (I was too chicken to try that).

No fungus gnats like soil and wet areas. You look like you have thrips or aphids. Aphids like leaves. So that’s my guess. I suggest using some Safers Insecticidal Soap. It works for multiple problems. Or the Safers 3 in one garden spray. Always good to have a little of this on hand for when issues arise. Hope that answers your question. Cheers. Good luck.
