What’s going on w my monstera?

I’ve had this guy for a few months now & he seems to be doing well, pushing out nice leaves (last pic) I don’t understand why some leaves have this brown discoloration? I’ve looked with a flashlight & don’t see mealy bugs, spider mites, or anything I’ve otherwise dealt with before. BUT, today I saw this small bug (3rd pic) on one of the leaves. No idea what it is, but I don’t visibly see any others anywhere else. Are these thrips? Ideas appreciated
