The hang-glider plent is the descendant of the gliding plent. It's bigger to capture more sunlight and catch more air to keep in it. The wingspan is approx. 10 meters. The adults never come down to the surface of Sagan 4 anymore because, from time to time, it will fly into a swarm of gliding sagworms to swallow some. From the sagworms it will get all the minerals and water needed for photosynthesis. When they fly into such a swarm, it is likely that some sagworms will hold onto the hang-glider plent to eat it, but for this, the plent evolved a trick. It will quicken so dramatically, that the feathers of the sagworms will catch so much air that the sagworms will be dropped from the plent. The legs fully degenerated, since it really never touches the ground anymore. Instead, it will follow the sun by flying into the sunlit half of Sagan 4. Thus, it will never sleep. It just has breaks, where it rests in the air while gliding. It replaces the gliding plent. Their young start as a normal flying plent, like other members of the genus Aeroflora.
