Metamorphosis is death. Inside a pupa larval flesh breaks down utterly, as if in chemical spill. Eyes do not become other eyes nor mouthparts mouths. All parts are lost in a reconfiguring slop, as absolutely formless as a salted slug, that ex liquid nihilo self-organizes into a quite other animal. A cocoon is not a transformation pod but an execution chamber, one that doubles as a birthplace, and is parsimonious with matter.
