So I found out what the butterflies are all about. I was able to ask the brand ambassador giving out free yogurt yesterday.
Apparently Alpina has paired up with WIN (Women In Need) to raise funds for the organization. Each butterfly represents a wish, and at the end of each week the butterflies will be released, freeing the wishes.

For every wish posted to Alpina’s facebook wall, the company will be making a donation to WIN.
Make a wish for the cause, it’s getting released on the wings of a butterfly:
