You have to catch an Ariados in route 229 an breed it and a spinarak will comme out from the egg
Ariados- More special attack and health! Hope this helps!
sorry to burst your bubble, but ariados can't learn shadow ball.
Once it is a level 24, it will evolve into Ariados.

Catch 2 Ariados, Breed them, and hatch the egg.
Good, somebody else loves Ariados! Well just catch a Spinarak and level it up to LVL 22, voila! Enjoy your cute little Ariados!
You can catch a spinarak north of cherygrove which evolves into ariados, but otherwise i don't know how to catch one directly

Catch an Ariados on route 229 (at night only) and breed it

go to route 229 at night and catch ariados, then breed it at the day care center by putting male/female ariados with your original ariados or breed ariados with a ditto which can be found in that BIG patch of grass west of canalave city, just use the pokeradar, and leave the Pokemon at the daycare for a few minutes and when you come back talk to the old guy, he will give you a spinarak egg, make sure you have a space in your party. enjoy your spinarak!Go to the resort area then catch spinrack's evoled form (i dont know what it is) catch one female and one male then breed.
Ariados doesn't evolve.
You need to evolve Spinarak, which can be found in FireRed on Pattern Brush (offshore island to the north of Fortune Island).
Ariados doesn't evolve again
It is in Route 229 but you have to catch it at night (which means after 8:00pm). You have a 20% chance of encontering one.
