According to an American Indian Legend -

If anyone desires a wish to come true they must first
capture a butterfly and whisper that wish to it.

Since a butterfly can make no sound, the butterfly can not reveal
the wish to anyone but the Great Spirit who hears and sees all.

In gratitude for giving the beautiful butterfly its freedom,
the Great Spirit always grants the wish.

So, according to legend, by making a wish and giving the butterfly its freedom,
the wish will be taken to the heavens and be granted.

We have gathered to grant this couple all our best wishes and are about to set these
butterflies free in trust that all these wishes will be granted.
