A cool morning warmed up under sunny skies as fourteen volunteers completed this week's survey. The iridescent blue on the Pipevine Swallowtail shown below is the result of structural coloration caused by light interference rather than pigment. The hue changes depending on viewing angle, causing the same transitory effects as are seen on a hummingbird's gorget or a peacock's tail.
