This close-up footage of butterfiles proves that what goes in, must come out.

In the video, butterflies drink water - and then emit a drop of pure-looking liquid spray.

According to the filmer, the yellow variety are King Swallowtails (Papilio thoas).

The footage was filmed at Betari's Natural Pool, in Núcleo Santana, at the Touristic State Park of Alto Ribeira (PETAR), in the town of Iporanga, state of Sao Paulo, Brazil.

Butterflies are such beautiful animals... it never occurs to us that they also pee, just like any of us... well, the equivalent of that, in insects. In this video you can see them drinking water and immediately eliminating the waste through the other end. That's a brand new look on butterflies!
