Have you seen this before. It is an ornamental sweet potato leaf. Under a hand lense, they don't move and are attached to the leaf. They are all white with maybe a small yellow dot. No legs, no face and intertwined. I thought some kind of egg at first but then I came across colleters. Anyone know or heard of that? I suspected spider mites but I never saw spider mites arranged like this before and they are bigger than mites.
This is the article.
