Paralyze, Sleep or Freeze.
A dark than fighting.
a luxry ball
Schyter or Pinsir.
Scyther and Pinsir are the best that you can find in the bug catching contest. Well i don't know if you can find a heracross or not...... sorry if i mistype the pokemon's name
In heart gold, you win the bug catching contest by catching the best bug type Pokemon. The score of the Pokemon you catch is based upon both it's stats and the amount of Hit Points it has left when you catch it.
I would use a master ball.
a hello kitty pokeball
any ball that you have the better the ball better the chances of catching it
the best Pokemon (grass) in platinum is probably shemin, but that's just my opinion - good luck catching it!!
Pokeballs are basic and arent that great at catching pokemon. Greatballs are slightly better. Ultra are the best quality to catch pokemon. Masterballs no matter what will catch the pokemon.
Butterfree for sure. With it's ability "Compound Eyes" it will have the highest accuracy of any status Pokemon out there.
greatballs catch them in 5 balls every time.
