Butterfly Beauty and a Beastly Habit
I recently was walking along the edge of a local river and encountered the inevitable goose poop along the shore. While humans may go YUCK when they see animal dung, our beautiful butterflies go YUM ! An all vegetable diet is often low in essential salts such as sodium, which is rich in animal excrement. So butterflies such as these tiger swallowtails commonly "puddle" on dung and sip up the salts which they need. So if you are looking for butterflies, follow a horse!
