|scientific name Chalcophora virginienis |
common name Sculptured Pine Borer or Large Flat Headed Pine Heartwood Borer
Boreal, jack pine forest.
Many names have been used over the years for this large and variable species (Bright 1987). Most western populations were called Ch. angulicollis Leconte, the sculptured pine borer and eastern populations Ch. virginienis (Drury), the large flat headed pine heartwood borer. I am following Bright (1987) where he includes both forms under the name Ch. virginiensis. This species, is the largest buprestid known to occur in Alberta reaching a length of up to 30 mm. The solid black colour coupled with the unique sculpturing on the elytra distinguish this species from all other Buprestid species in Alberta.
Adults are known to oviposit around scars on living trees, on stumps and logs (Baker 1972). The specimens found near Clyde were resting on fire blackened trunks of jack pine, burned the previous year.
In the literature the beetles are reported to feed on a wide variety of conifers including jack pine, lodgepole pine and Douglas fir (Barr 1971, Baker 1972, Bright 1987). In Alberta adults were associated with charred jack pine.
Transcontinental in Canada and south to Mexico (Barr 1971, Baker 1972, Bright 1987).
