Chalcophora angulicollis
western sculptured pine borer, sculptured pine borer
Chalcophora angulicollis is a large metallic wood-boring beetle in the family Buprestidae, commonly known as the western sculptured pine borer. It is one of the largest jewel beetles in western North America, measuring 20–33 mm in length. The species is strictly associated with pine trees (Pinus spp.), where larvae develop in dead or dying wood. Adults are active during daylight hours and are frequently observed running on or flying to recently fallen or injured pine trunks and branches. The species was historically confused with the eastern Chalcophora virginiensis but was reinstated as valid based on distinct morphological differences in mouthparts, male genitalia, and elytral margins.
Chalcophora liberta
northeastern sculptured pine borer, smaller flat-headed pine borer
Chalcophora liberta is one of five North American species in the genus Chalcophora, commonly known as sculptured pine borers. It is among the largest jewel beetles in eastern North America, characterized by its metallic coloration and heavily sculptured exosurface. The species is strictly associated with pine trees (Pinus spp.) and is one of four eastern species in the genus, distinguished from congeners by specific morphological features including coloration and male genitalia structure.
