in the petalburg woods right off of route 104 (directly in front of the rich boy)
it evolves at level ten.
Silcoon will evolve at a low level because bug Pokemon evolve quickly.
Cascoon and silcoon evolves at lv 10 (i hope i helped)
You cant. You have to put silcoon in the front of your party and when you get into a battle you switch out and defeat the Pokemon and silcoon gets exp. Or use n exp share. Silcoon will evolve at i think lvl 12.
In Pokémon Ruby, you can obtain Silcoon by evolving a Wurmple. To do this, catch a Wurmple, which can be found in areas like Route 104 and the forest near Oldale Town. Once you have a Wurmple, level it up to level 7, at which point it will evolve into either Silcoon or Cascoon, depending on its individual characteristics. Silcoon evolves into Beautifly at level 10.
Silcoon is a Bug type pokemon.
Silcoon evolves at level 10, as does Cascoon.
you can get a silcoon either in eterna forest or by evolving a wrumple which as well you may get in eterna forest.
Pokemon ruby's version IS Pokemon ruby.
You can catch Silcoon in White Forest.
Eterna Forest, only during the night though!
U can find Silcoon in the Petalburg Forest
