Question: Can I release my butterfly at any age to get Bpoints?

Answer:

You can release your butterfly at any age to get Bpoints, but the amount of Bpoints you receive depends on its age. The younger the butterfly, the fewer the Bpoints, while older butterflies (up to 30 days) will yield more Bpoints. However, releasing is only available for butterflies under 30 days old.

If your butterfly is 31 days old or older, you cannot release it. Instead, you must send it to heaven using the Ascendia Potion, which is free of charge. Sending an Elder butterfly to heaven will reward you with the full Bpoints for its age, but the butterfly will no longer exist in the game.
