What does a witchery grub turn into?

A witchery grub, which is the larval stage of a moth known as the "witch moth" (family Noctuidae), eventually transforms into a moth. Specifically, it undergoes metamorphosis, emerging as an adult moth that typically has dark, muted colors and is sometimes associated with folklore and superstition. The transformation process includes stages of egg, larva (grub), pupa, and finally, the adult moth.
