Phoebis sennae, the Giant Cloudless Sulphur butterfly, brings flashes of bright yellow to flower beds and humankind from South America to southern Canada. This butterfly moment catches it navigating its way through tall vegetation. With its head frozen and its wings a blur of motion, this one-in-a-million field shot catches it head-on as it crosses the field of focus. This version of the image comes with a dark simulated mat border with drop shadow. By Dwight Bennett from Natureworld Art.
