Its a longhorn beetle (Cerambycidae). I am not sure about the color, there are some different out there, but the shape is nearly the same of all beetles.
Yafaray does not do any calculated displacement. You create displacement by applying enough subsurf (modifier) levels to your mesh and use the Blender displace modifier, ie. you displace the mesh inside Blender.

I don't know what you mean with 1 to 1 copy, but you meet all the requirements to remain in the competition. IMO, the bug need no to be 100% exact as in nature, if that's what you are asking.
