Chrysochroa buqueti II
Chrysochroa buqueti (Metallic woodborer beetle, “Jewel Beetle”).
I had posted a couple of other images of this beetle back in October.
Detail of carapace. Shows iridescent color pattern caused by structural color. This is created by nanostructures in the surface of the carapace.
Nikon MM-11 microscope, Mitutoyo 5/0.14 M Plan Apo objective, Olympus U-SWTR-3, Canon T3i camera.
The section in this second picture fascinated me. It is a very small area on the bottom of the head, just behind the mouth. Just seemed like an odd place for such a dramatic "color show"... after all who/what would ever see it!?

Charles, nice to see you posting true masterpieces again!
Not all features of living beings have a direct adaptative function. Maybe it could be just the expression of the same genes that control the general coloration of the more visible parts of the beast. The natural selection can not promote nor eliminate this character (adaptatively neutral).Charles Krebs wrote:The section in this second picture fascinated me.
