If you’ll excuse the poor sharpness in the following sequence, I’d like to share some food stealing behavior I observed and captured between two juvenile hemipterans (mesovelids, I believe).

I also witness the red dragonfly mating, so I can now identify the female.  After mating, the male took up a peculiar posture 10 cm above the female, and chased away other males as they approached (mate guarding).  He continued while she deposited eggs.  Soon, however, a rush of other males came in and the female took off.  The original male remained and defended the area, although I’m not quite sure why.  Further, the male also chased off all other dragonflies, including several individual dragonflies that were completely black, which I assume are another species.
