I have a Burrageara Nelly Isler and it has black spots all over it, almost as if it was spray painted. Upon closer inspection I see tiny tiny bugs crawling on the leaves. I don't have a magnifying glass and they are small enough that I can't see any details and can only say that they appear to be longer than they are wide, are black and are smaller than the spots on the leaves. I have attached some photos hoping someone could tell me what these are.
