And sometimes their history of metamorphosis is used to show transformations less drastic than total rebirth. (Because butterflies are also ethereal and can fly, if this is a moral transformation, it is more likely to be a HeelFace Turn than the other way around.)
Caterpillars can also work, and bonus points for the entire transformation in story. Moths can also be used, but then you don't get Pretty Butterflies, and besides, moths are nocturnal (fictionally, at least), and you know what that means.
- In Sailor Moon a butterfly motif is heavily featured in the titular heroine's "Crisis Make Up!" Transformation Sequence which sees her power up from Sailor Moon into Super Sailor Moon in the third season Sailor Moon S. This is not only touches on this trope but also draws on the way the Butterfly of Death and Rebirth trope is used elsewhere in the season, a particularly evocative version shows up using the power of the Sailor Soldiers themselves rather than via the usual Holy Grail Transformation Trinket that was in hands of the enemies in the penultimate episode of the season which is given its own animation.
- Butterflies are one of the motifs of Yes! Pretty Cure 5. A butterfly has to land on the chosen human's wrist to become the Cure's Transformation Trinket, and the phrase used to turn into one for that team is "Precure, Metamorphose!".
- In his various Cupid and Psyche paintings, William-Adolphe Bouguereau will often depict Psyche baring moth or butterfly wings, representing her metamorphosing into a goddess, as though emerging from a chrysalis.

- Vic Sage's last words in 52 invoke this symbolism of butterflies. They are addressed to Renee and foreshadow her transformation into the new Question.
- Psylocke's telepathy is symbolized by butterflies, and her character has undergone tremendous change, having switched bodies, become Captain Britain (twice), gained new psychic powers (twice), and joined the X-Men. Her successor Kwannon inherited the butterfly motif via a Retcon; she views her changes post-revival as a metaphorical rebirth, fitting the sub-trope of Butterfly of Death and Rebirth.
- In Mutts, witnessing a catepillar go through it inspires thoughts of change, such as Mooch's observing that someday, Earl might become a cat.
- In the book/movie Silence of the Lambs, Jame Gumb keeps butterflies or moths, and they seem to symbolize his desire to transform into a woman.

- The caterpillar in Alice's Adventures in Wonderland can be seen to serve this sort of symbolic function.

- The I Am Legend remake features the motif of a butterfly quite often. In the released film, it doesn't amount to anything; however, in the original ending, it represented that that the Dayseekers weren't mindless, evil zombies, but sentient beings that had transformed into a better forms than the old-fashioned humans. Keep in mind that "better" is in the eye of the beholder.
- In Cinderella, Cinderella's gown from the Fairy Godmother has butterfly decorations around the neckline, as well as on her shoes, as a motif of her transformation.
- Rose's butterfly comb and kimono with wing-like sleeves in Titanic (1997) serve as symbols of her change into a confident woman in control of her own destiny. The butterfly motif is explicitly stated in a piece of dialogue that was later cut from the film.

- In Gene Stratton-Porter's Freckles, Freckles watches in wonder as a Luna moth comes from its cocoon and feels deeply frustrated at his ignorance at what it is, though he knows it's not a butterfly. This causes him to ponder his ignorance, until it dawns on him that he could find out these things.
- In Terry Pratchett's Discworld novel Making Money, Cosmo Lavish uses a caterpillar becoming a butterfly as a symbol of his own planned transformation. His sister Pucci tells him that what actually happens is a caterpillar dies and a butterfly grows out of the remains.
- The Animorphs book The Departure heavily features the theme of a caterpillar, and later a butterfly. It is not a coincidence that this is where Cassie meets a surprisingly sympathetic yeerk, one willing to give up her host body if Cassie is willing to experience the rest of her life as a Yeerk... or the closest thing at hand: a caterpillar. This, along with Cassie's continued realisation that the world isn't as black and white as she thought, signifies change. It also brings up the fact that natural metamorphosis can somehow undo the Mode Lock of remaining more than two Earth hours in morph, something Cassie willingly did to make the Yeerk free her host.
- In Sarah Addison Allen's The Girl Who Chased The Moon, when Emily's wallpaper changed for the first time, it changes to butterflies. They seemed trapped and wanting to escape.

- In The Adventures of Caterpillar Jones C.J.'s journey is both a literal and symbolic form of this trope, as he literally transforms from caterpillar to butterfly and, in doing so, symbolically lets go of what's holding him back and embraces his new life.
- If one goes with the interpretation that the title of Chrysalis refers to the smooth, elongated form of the Terran's mechanical outer shell, it can then be extrapolated that the Terran's destruction, and thus emergence from their cocoon, are evocative of the rebirth of humanity in machine form. The epilogue reveals the Terran was revived from their fragments and placed back into a humanoid body, as well.
- In Babylon 5, Delenn uses a butterfly-like cocoon to transform into a half-human half-Minbari. During the transformation, the security team exploited the trope by telling the traitor that it she became beautiful as she left the cocoon, as if she was a butterfly with wings.

- In Doctor Who, the Second Doctor compared his regeneration to a renewal like a butterfly emerging from its chrysalis. Which is why the ring no longer fits.
Doctor: I'd like to see a butterfly fit into its chrysalis case after it's spread its wings!
Polly: Then you did change!
Doctor: Life depends on change and renewal I've been renewed. It's part of the TARDIS. Without it, I couldn't survive.
Polly: [to Ben] It's a very different Doctor, then.
- Kamen Rider Fourze pulls this in The Movie with Inazuman, another Shotaro Ishinomori creation. At first, Saburo Kazeta is a bitter young man who hates "normal humans" for shunning him due to his psychic powers, which include transforming into the larval Sanagiman. Fourze gives him a heart-to-heart (which outright includes the butterfly metaphor) which leads to Saburo pulling a HeelFace Turn, at which point Sanagiman "molts" into Inazuman, complete with radiant wings.
- Marilyn Manson's Antichrist Superstar album is a narrative about a child's transformation into the antichrist (/a controversial rock star).

- In Charlie and the Chocolate Factory (the 2013 West End musical), Willy Wonka has an I Am What I Am song, "Simply Second Nature", in which he explains his inborn need to create beautiful — if strange to some — things. At one point, a sudden wave of his cane reveals a butterfly perched upon it, which continues this adaptation's running motif of humble things that contain/conceal great beauty and possibility (tying in to the Central Theme of the transformative power of imagination).
- In the Persona series, the golden butterfly is symbolic of Philemon, the deity that allows the heroes to tap into their Personas. According to Word of God, in the later games in the series he actually appears as a blue butterfly with an implied similar, if lesser, function, although neither the characters nor any narrator identifies him.
- This is part of Morph Moth's gimmick in Mega Man X2. He starts the fight in a cocoon suspended on a thread, and after taking enough damage he, appropriately enough, metamorphosizes into a fully grown robot moth.
- In BioShock 2, Rapture's change as "better" society fueled by Dr. Lamb's extreme altruistic view are symbolized by a blue butterfly that is worn by most of the members of the Rapture family and it appears in most of the city. A lot of the graffiti with this motif also reads: "We will be reborn in the cold womb of the ocean. She is our savior". Turns out more literal than you would think, as Lamb's plan is using her own daughter as a "database" of the population of Rapture to create a human completely driven to benefit a group in its entirety.
- In Cultist Simulator, the symbol of the Change Ambition is a butterfly cocoon, and advancing the Ambition card gradually hatch it to reveal a pretty butterfly emerging from it. However, the descriptions of what actually happens are anything but pretty.

- Fatal Frame II: Crimson Butterfly has butterflies everywhere as the motif associated with the twins of All God's Village, referring to the death-and-rebirth interpretation, the identical-halves-of-one being interpretation, and ultimately ending on the transformation interpretation: The souls of the sacrificed twins literally become butterflies. Mayu is released from the "cocoon" of her body by the red, wing-shaped handprints Mio leaves on her throat.
- The fourth entry in the Gears of War series introduces JD Fenix and Kat talking about how a cocooned butterfly changes its shape just before they go on a raid.
