Diadasia australis, M, side, Pennington, SD

A common genus out West, this genus does not really make it to the wet and lush East. This specimen we collected in the Badlands of South Dakota in the park of the same name. Clair Mudd took the shot. Photography Information: Canon Mark II 5D, Zerene Stacker, Stackshot Sled, 65mm Canon MP-E 1-5X macro lens, Twin Macro Flash in Styrofoam Cooler, F5.0, ISO 100, Shutter Speed 200. USGSBIML Photoshopping Technique: Note that we now have added using the burn tool at 50% opacity set to shadows to clean up the halos that bleed into the black background from "hot" color sections of the picture.
