hi

Combee can rarely be found on Sweet Honey Tress (that is, trees with orange leaves) if you put a lot of honey on it. Most of the combee you'll find will be male, but in order to evolve Combee into Vespiquen, you need a female Combee.

Now, Arceus isn't caught through a simple process. First, you need to obtain the National Pokedex (obtained from Oak in Rowan's lab in Sandgem Town once you've seen all 150 Pokemon in the Sinnoh Pokedex) and have beaten the Elite Four. Once you've done that, you need to obtain the Azure Flute through cheating, or by attending a Nintendo Event (which are currently held in Japan and won't be held in the U.S. For a while. If you live elsewhere in the world, you're pretty much left with traveling, or by using an Action Replay.)

Once you have the Azure Flute, you need to go to the top of Mt. Coronet (Spear Pillar) and use the Azure Flute. Stairs should appear in front of you. Go up the stairs, and you'll be in a place called the Hall of Origin. At the top should be a level 80 Arceus.

Arceus is an Event Pokemon, So youll have to go to an Event aboyt Arceus. Then again you can cheat or hack by using Action Replay or maybe Game Shark. Combee can be foundIn most routes like the routes Hear Heathome City.
