This past summer, I had the opportunity to participate in the NSF REU at Sevilleta National Wildlife Refuge for art & ecology. The iridescent beetles and hummingbirds I encountered around the refuge sparked my curiosity, not only about how they produced such dazzling colors, but also about what functions these adaptations might serve. So for my final project, I researched the physics behind iridescence and its ecological role, creating this booklet with paintings, drawings, and diagrams.
