Caterpie is #10 in the national pokedex, and it is a Bug type Pokemon.
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.
