Biting Stonecrop - Sedum acre in reflected ultraviolet photography, simulated butterfly and bee vision

Today shots of a decorative flower, a small creeping Biting Stonecrop - Sedum acre in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating bee and butterfly vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sun. All shots were done at about f5.6.
