The Xerces Society was founded by award-winning nature writer and lepidopterist Robert Michael Pyle in 1971 (which means we'll be 50 next year). Bob remains part of our work and has been a constant counselor. In addition to his many other achievements, one of Bob's books has now been made into a movie.

Starring David Cross and Debra Messing, The Dark Divide tells the tale of Bob's expedition through Washington's Gifford Pinchot National Forest in search of new species of butterflies, during which he "battles self-doubt, the grueling trail, and the people and creatures who call this forest home. And, somewhere deep in the heart of The Dark Divide, he makes a discovery that challenges everything he knows about the natural world."

The movie is showing in some theaters, but Xerces supporters can get $5 off the streaming rental. Go to The Dark Divide website, select "Virtual Cinema" and then click on the Xerces Society logo. When you get to the checkout, enter XSDD5 for your discount.  Rent the movie
