Not a thrip. A is probably about 5% that size - super tiny! And, they hang out in the flowers mostly from my experience. I believe that is a winged aphid. Not problem unless the numbers get huge.
That could be a type of mold, but, I'm uncertain. Have you been using fungicide or some sort of protectant like Daconil? If not, (or even if so) that could be a gray mold or black mold. Either one is bad news because they are almost always more wide spread that what you see. They are difficult to treat if established. You could try removing all affected foliage and spraying with a funigicde, copper for example and see what happens. Bill in Alabama uses his bleach spray immediately. It will kill molds, but, it will taken down all affected foliage and that could be a significant amount, based on what we see in these pics.
