So, we're trying out a more bat like approach, huh. Well, I'm gonna through out my sketchy design idea. What if there was more focus on the tail? In most of the evolution ideas, I don't really see anything incorporated with it. The first stage having a stem tail, the second could have leaves for the awkward middle stage and the final having a flower-esque tail - working it's way up to a flower. This ties in well with the idea of having a more mischievous and mean spirited fairy approach as it ties in with the Australian lore of feral fairies which leave magic dust that causes weeds to grow.
See http://www.mythocreatology.com/Shadow.html The stamen tips of the final evo's tail could leave behind pollen that causes weeds to grow as it flies or something.
