You mean Ariados? It evolves from Spinarak which is like one of the first Pokemon you find in the game..
I do not believe it can be caught in the wild. You have to level up a spinarak to 22. And it's spelled ariados
I'm afraid not.

Silaqueen is not an existing Pokemon. It is not found in HeartGold or any other version. It will be found no where.
Ledyba is not catchable in Pokémon HeartGold Version.
Pokemon HeartGold and SoulSilver.
You can only go to Johto and Kanto in Pokemon Heartgold and Soulsilver
The only way is to throw away your Heartgold version, buy the original Red version, and play a real Pokemon game.
