Gliding Sagworm

After a long period of stability the feathered silkworm was pushed to evolve by the emergence of a number of new environments, namely the warm and teperate forests and plains of the super continent. The abundance of vegetation and lack of predation in these environments allowed the sagworm to increase in numbers hugely, to the extent they feed in an almost unsustainable fashion. The feathers on their back have extended to catch the wind, and the body of the worm has grown lighter. Consequently, the worms lives are governed by the winds. Forming gigantic 'swarms' the worms are blown from place to place, wherever they land they feed voraciously until no vegetation remains. A chemical signal released by hungry worms prompts the superswarm to take to the air (using their silk strands to gain the initial lift required) where it drifts until the wind once again drops and lands them in a new feeding location. Due to this pattern of behavior Sagworms can be found all over the continent, as long as there is vegetation and it doesn't get too cold. Their main predators are the various flying Plents, although even their predatory action can not significantly dent the global Sagworm population.
