Chalcophora virginiensis (Drury), the large flatheaded pine heartwood borer, 
breeds in injured, dying, and dead pines and in pine stumps throughout the Eastern 
United States. Adults (fig. 122) are dull-black or dark-bronze beetles about 23 to 33 
mm long. The thorax is broader than long, and the elytra are marked with dark or 
shiny elevations and rough, grayish or brassy depressions. Full-grown larvae are up 
to 50 mm long and the dorsal thoracic plate is marked with a Y. Eggs are deposited 
around scars on living areas and in bark crevices or holes in the bark of logs and 
stumps. Living trees may be severely damaged by larval tunnels in the wood. Pine 
logs left too long in the woods are also subject to severe damage. C. liberta 
(Germar) and C. georgiana LeConte are often found in association with C. 
virginiensis. Adults of C. liberta are copper or brass colored, while those of C. 
georgiana are golden bronze. 
Chalcophorella campestris (Say), the flatheaded sycamore-heartwood borer, 
breeds in injured, dying, or dead sycamore, beech, oak, maple, yellow-poplar, and
