i have only seen about 8 of them , 3-4 on my glass and the rest on my rock the few on the rocks seem to be turning brown. They started out a bright white. After being on the glass they release and float around a bit, and they are about the diameter of an eraser on a pencil. That pencil would be a #2 wooden pencil (LOL)
