Can't say for sure from the pic but if your plants look fine it may be Hypoaspis miles. If noticing damage may be a root aphid. With a better picture you can tell the difference.
Shit just see pics of hypoaspis miles its same. I spray coco surface with poison and kill them. They are good guys eah. I can't snap better pics but I looked throught 55x loop and its same I also check to see RA anthenas but this ass is just oval. No anthenas. And plants is fine.
Many thanks.
