ANSWER:nobody in platinum owns the caterpie evolution line
To add caterpie to the pokedex in Pokemon platinum, you must first get the national pokedex, and then migrate him from pal park (if you havent already done that), and finally catch him in pal park and he or she has been added to your pokedex.
You can trade, use the action replay for Pokemon Platinum, or actually catch it without the action replay. If you have completed the Sinnoh Pokedex, go and see Professor Rowan, and he will give you the National Pokedex, then you catch all the Pokemon throughout the land of Sinnoh from all the other regions due to an "outbreak". But, where to catch caterpie specifically, you need to go to Eterna Forest, west of Eterna City.
caterpie dosen't evolve into beutifly, its last evolution is butterfree
You have to trade it from firered etc.
You can catch a caterpie or metapod at the national park north of goldenrod city. After you catch the caterpie evolve it to a Metapod and then evolve it to a Butterfree.
Caterpie
you cant. In gold you cant catch weedle. i have a handbook
to catch a caterpie, you must first have poke balls and some weak pokemon. you weaken the caterpie down to red health and the throw your poke ball. if this does not work, keep on throwing your poke balls until it eventually works. hope this helps.
You can't catch one
You can't catch a wild butterfree in Pokémon fire red. You have to catch either a Caterpie or Metapod and evolve them. Caterpie evolves at level 7 and Metapod evolves at level 10. Have fun! :)
i would, my OT:is ash and ill want something like a bibarel or so cause i dont really need a caterpie,
