Entomologist and adventurer Phil Torres hosts a popular YouTube Channel, The Jungle Diaries, where he shares insights and observations from his travels to remote areas around the world. Recently, a trip to the Peruvian Amazon afforded footage of eight different butterfly species alighting on turtles to drink their tears. The phenomenon occurs because the sodium in the tears is a vital part of the butterflies’ diet that’s not readily available in the foods they consume. The search for sodium is actually quite common in the wild, and is also sourced from jaguar feces and river mud, as Torres notes.
