The second, third and fourth shots depict some strange goings-on under the abdomen. Almost looks like something is comming out the side of the abdomen in the third shot. The preceeding and following posted shots don't show any of this, and it's clearly not part of the plant. The fifth shows liquid (honeydew?) being "shot" from the hopper's rear. I took many shots trying to capture a "ball" in flight, but it all happened in milliseconds, though at regular intervals, and this was the closest I came.
