Apparently, this phenomenon occurs because these Julia and Sulphur butterflies require sodium to live.
Far away from a source of salt, they rely on salt-rich turtle tears.

OMG LOOK AT THESE BUTTERFLY KISSES! THEY JUST WANT HIM TO BE HAPPY, I KNOW IT!
Luckiest. Turtle. Ever.
But one question remains: why are the turtles so sad?
