Evolve now or wait
from the game's learnsets and the relearner ruleSilcoon evolves at level 10. Nothing is lost by evolving straight away: every move Silcoon learns after that, Beautifly learns too. Beautifly learns 8 moves of its own after that: Gust at 13, Stun Spore at 17, Morning Sun at 20, Mega Drain at 24, Whirlwind at 27, Attract at 31, Silver Wind at 34, Giga Drain at 38.
Rule the game applies: the Move Relearner in Fallarbor Town (he takes a Heart Scale) teaches only the level-up moves of the form you hand him, at or below its current level. Delaying an evolution costs the evolved form's higher base stats for every level you wait; a move you barely use is not worth that.
