    That tracks. I wonder why some animals do that and others don’t. It’s not like there’s much natural uv in any situation lacking visible light

      Ah, but “visible light” as a category is human-centric in that it’s based only on which wavelengths of electromagnetic radiation our eyes can detect or “see”. Other species can see more or different wavelengths, such as UV.
