this little guy was so colorful that I had to get a picture. But he (or she, no idea) was fast and would not sit still for a moment. I was following it around snapping shots in “machine gun” mode hoping to get something usable for about 15 minutes till I finally felt kind of strange with people walking by staring at the weirdo with the camera chasing a little beetle around.
