A beautiful little video of some rather amazing gymnastic maneuvers employed by this American Rubyspot to groom himself. Here's the description from my friend Meena Haribal who filmed the behavior:
A male groomed his body, possibly to rid of parasites such as mites. I personally did not see any mites on him, but I guess he was not taking any chances. He shook his abdomen several times, then cleaned it with his hind legs. Then the hind legs were cleaned by rubbing each other, Eyes and face were also cleaned several times. The forelegs were then cleaned with mouth and mouth was also cleaned as we gargle and brush.
