To be honest it’s really hard to tell from the pictures but if they move them they are most likely a type of spider mite! Look on the under side of the leaves 🍁 using a jewelers loop or a microscope and this will give you a for sure of what your dealing with! There is a few different types of mites but I suggest treating ASAP as the longer you wait the harder the issue will be to get under control as the mites manifest quickly! Good luck 👍🍀
