The pupal stage of a butterfly or moth, often encased in a hardened protective shell.
From Latin 'aureus' meaning 'golden,' because many butterfly pupae have a golden or metallic appearance. The term was formally adopted into scientific English in the 1700s as naturalists classified insect life stages. The suffix '-ia' creates a feminine Latin-style noun.
Inside an aurelia, something miraculous happens—the caterpillar's body basically dissolves into a liquid 'soup,' and the organism completely reorganizes into a butterfly, a process called 'metamorphosis' that's still not fully understood by science! Some researchers think certain memories or instincts might somehow survive this complete transformation.
