| I second what the others have said. My picture is a little small but they look like a hard scale insect to me. When you squish them with your fingers are they juicy, sticky or hollow, dry? If juicy, sticky they are alive till just then. If dry, hollow they are dead, maybe something else eat them, maybe old age. Even if they are dry, hollow they should be washed off, there can be eggs underneath. Look very carefully at natural leaf veins and the tender young parts of plants for almost clear little bumps, that would be the young scale be sure to wash those off too. A small hand lens or magnifying glass can be very helpful here. Look equally closely at a healthy plant to see what should be part of the plant and what is other or damage.
