A maggot transforms within a pupa and a fly emerges in this Maggot to Fly Transformation video, filmed by Ammonite Films. Watch as an inflatable head sac called a ptilinum helps push the fly out of the puparium, a seemingly difficult process. But what’s happening inside the larval shell as the maggot turns into the fly? We don’t quite know the details… yet. Watch. What do you think?
