Turtle Tears are a Delicacy for Amazonian Flying Insects

This is quite intriguing, and beautiful to observe - butterflies and bees in South America have developed a taste for the tears of turtles.

The butterflies are likely attracted to the turtles' tears because the liquid drops contain salt, specifically sodium, an important mineral that is scant in the western Amazon, said Phil Torres, a scientist who does much of his research at the Tambopata Research Center in Peru and is associated with Rice University.
