Viceroy butterfly, a close mimic of a Monarch. I seen them rarely, and always in the same place. Curiously, there is a big willow nearby, and willows are reported to be the preferred food for Viceroy caterpillars. The camera chose to focus on the grass behind the butterfly, but you can still see the black band across the hind wings which is the easiest way to tell them from Monarchs.
Tiger shark (contortus) tooth as found.
C-130 to me.
