Lumbering pairs can be seen stumbling into patches of jelly-bladder plants. With greedy abandon, the awkward creatures rip into the wobbly bags of vegetable gel and drink their fill through their hyperextended proboscises. It is not long before the first bladders are shriveled husks, their liquid drained or spilled.The glutted gel-suckers then move methodically from one bladder to the next, ripping them apart, apparently for sport. Gel tumbles and cascades out in big chunks, melting into lumpy puddles on the ground. As each jelly-bladder is destroyed, dozens of small, pinging hoppercones appear from their tunnel nests to snatch pieces of semisolid bladder skin.
