Hi! I can't figure out what is attacking my house plant (some kind of palm). It lives indoors, though close to a window which is often open. These white dots just appeared in the last few days or so, but I've been pulling off brown leaves for a couple of weeks. Is this scales? Mealybug? Spider mites? They are almost exclusively on the top part of the leaves rather than the underside. They don't seem to be moving around. Some look more like scales (rounder) but most look like tiny grains of rice, some a bit fuzzy, but no webs. I also see the white dots closer to the stem. Any help would be appreciated! I live in Germany. I've put the plant on the balcony for now to avoid the creatures spreading to other plants.
