I struggled to get a decent picture of them--- and all but failed as clearly as their attempt to not be noticed.
B noticed this one moving on the ground: it was being carried by an ant.
I came across tiny, white moths once before many years ago. We were camping at Vogel State Park in the mountains of north Georgia. As the evening cooled, I had donned a long-sleeve, white silk pull-over. Dozens of tiny white moths began to gather and were drawn to the light of the lantern, and then to my top. It was kind of magical as they fluttered and lit on the shirt. I have to wonder if it was the whiteness reflecting the lantern light or if, perhaps, they could detect the silk worms that had made the fibers.
