Cochliasanthus caracalla is quite the name for this plant. Snail vine seems a much easier thing to say … and I can see why they might call it a snail vine. (Caracalla comes from the Portuguese caracol, which means snail.)
The bug is small, but I’m sure you can spot him if you look carefully. Truth be told I did not see him when I was shooting the flower. I was too interested in this plant that was new to me.
