Best Silcoon IVs by league
| League | Rank 1 IV | Lv | CP | 15/15/15 |
|---|---|---|---|---|
| Little | not eligible — must be unevolved and able to evolve | |||
| Great (under cap) | 15/15/15 | 50 | 626 | #1 |
| Ultra (under cap) | 15/15/15 | 50 | 626 | #1 |
| Master | 15/15/15 | 50 | 626 | #1 |
Silcoon cannot enter Little League, because it has already evolved. The format takes only Pokémon that have not evolved yet and still have an evolution ahead of them — the 500 CP cap is not the only rule.
Silcoon never reaches the 1,500 CP cap of Great League or the 2,500 CP cap of Ultra League: at level 50 it maxes out at CP 626. In those leagues nothing is held back by the cap, so the highest IVs simply win and 15/15/15 is best — the same as in Master League.
Rank 1 IVs across the evolution line
IVs never change when a Pokémon evolves, so the spread you want depends on the league you are building for.

How to find a good Silcoon
The search-string generator builds a string you can paste into the search bar in Pokémon GO. It finds catches whose CP, HP and appraisal stars match the top IV spreads above, including pre-evolutions, so you can check a whole storage box in one go.
To check a Silcoon you already own, open the IV ranker and set its IVs.
