Coleoptera: Buprestidae; The Metallic Wood-boring Beetles or Jewel Beetles. This 18mm specimen is probably a Flat-headed Hardwood Borer (Dicerca divaricata). Heavily pitted body appears to be armor-plated.
Top photo: Flash angled to emphasize the metallic reflectivess of the body.
MF 105mm Micro Nikkor @ full extension, f/8 on lens, + 140mm extension. 50 frames @0.1mm HF4.1.

Bottom image to show body shape, flash diffused to minimize relections.
Recently aquired voucher specimen, 12x08.

Beautiful - you have many more Dicerca species in N-America than we have in Europe.

I can confirm that - I once tried to pin a Capnodis sp. from the Mediterranean. I applied such a pressure that the round end of the pin penetrated my finger while the acute end had hardly made a dent into the integument of the beetle Confused

Cheers

Thanks Harry. This seems to be the most frequently seen species but they are nowhere near as common as Cerambycids, especially Monochamus scutellatus

Excellent detail on the metallic surface. My second favorite group of beetles (Tigers are my first).
