Cloudbubble Tropoworm

After the second generation of atmospheric ecosystem was destroyed during the mass extinction at the end of the Bloodian period, the tropoworm and herbivorous tropoworm's populations crashed due to the lack of substantial amounts of food. The once numerous swarms dropped to groups containing only a handful of individuals as the species grew increasingly rare. However, with the evolution of the marbubble, and later the cloudbubble, the third generation of atmospheric ecosystem is dawning, and the herbivorous tropoworm was quick to jump at the opportunity of being successful once more. As a result a population split from their ancestors and began feeding on the cloudbubble.

The cloudbubble tropoworm has adapted to better survive in the troposphere. Their wings have become more broad, allowing them to fly with less effort. This allows them to conserve energy, which is hard to gain in a largely barren habitat like the troposphere. Their once-rough gray segment has become smooth, making it more aerodynamic, allowing it to fly with greater ease. They have also grown smaller, decreasing the amount of nutrients needed to spend on growth. In order to feed on the cloudbubble, their lower mouth bristles have been modified into simple mandibles, which allow them to grab and pop cloudbubbles before flying forward to swallow the cloudbubble's remains. Their mating ritual also centers around cloudbubbles, in which they will lay their eggs on cloudbubbles due to them being the only available surface to deposit their eggs on. The larvae hatch at a size of 1 mm long and can fly from birth. They use their upper mouth bristles to aid them in filter-feeding, which will sustain them until they reach their full size. Only then can they begin feeding on cloudbubbles.
