Sculptured pine borer
Chalcophora virginiensis
A species of Chalcophora, Also known as Western pine borer, Larger flat-headed pine borer, Large flathead heartwood borer, Jewel beetle
The Sculptured Pine Borer or Chalcophora virginiensis is a metallic woodboring beetle of the Buprestidae family. It is endemic to forested areas in the eastern United States and Canada. Some authors have synonymised it with the western species Chalcophora angulicollis, but Maier and Ivie (2013) demonstrate that the species are distinct.

Life Cycle of Sculptured pine borer
Egg The embryonic development of sculptured pine borer occurs within the egg, resulting in a small larva ready to emerge. The eggs are often oval, laid in clusters, and vary in color from translucent to a more opaque hue.
Larva As larvae, sculptured pine borer appear worm-like with a soft, elongated body, varying from white to cream-colored. Their primary function is to feed and grow, undergoing several molts and size increases.
Pupal During pupation, sculptured pine borer undergoes transformation within a protective casing. Initially, the pupa might resemble the larval form but gradually takes on the adult features. Color and form changes are dramatic as tissues reorganize.
Adult Emerging from the pupa, the adult sculptured pine borer’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

How Can You Attract Sculptured pine borer
People may use pheromone traps or visually appealing structures to attract adult sculptured pine borer, as they are drawn to specific scents and visual cues for mating and feeding. Larval stages of sculptured pine borer are often found within wood, thus traps for larvae might not be applicable.
Habitat Preferences of Sculptured pine borer Through Different Life Stages
The larvae of sculptured pine borer typically dwell in the decaying wood of various deciduous trees, often oak and pine, where they feed and develop. To find these, one should search in old forests with abundant fallen logs and stumps. The adult sculptured pine borer prefers the canopy layer of mature forests, where it seeks mates and lays eggs on the bark of weakened or dying trees. Seeking adults involves scanning the trunks and lower branches of trees, paying particular attention to trees in distress or those with peeling bark. To observe pupae, one might carefully split open infested wood, though this is rarely done due to the potential harm to the specimen.
When is the Best Time to Observe Sculptured pine borer
The best time to find adult sculptured pine borer is during warm months, typically in late spring and summer when they are most active. The larvae can potentially be found year-round within their wood host.
What is the Best Weather to Observe Sculptured pine borer
Adult sculptured pine borer prefer warm and sunny weather for optimal flying conditions. Humid or rainy weather may make them less active. It's best to look for them on dry days with little wind.
How and Where Can You Find Sculptured pine borer at Different Life Stages
Larva Sculptured pine borer larvae are wood-borers and can be found by examining host trees for exit holes and frass. They are typically found by carefully splitting infested wood or peeling back bark layers on dead or dying trees.
Pupal Pupae of sculptured pine borer develop within the wood where the larvae fed. Finding pupae involves searching in similar locations as larvae, but closer to the anticipated emergence time when pupae might be closer to the wood surface.
Adult Sculptured pine borer adults are often found on trees, logs, or other wooden structures. They can be located by visually searching these areas or by using attraction methods such as decoys or pheromone traps.

Forestry Pest
Adults and larvae of sculptured pine borer bore into stems and roots, causing dieback and structural weakness in coniferous and deciduous trees. Infestation can lead from mild stress to severe tree mortality, with extensive damage inviting secondary pests and diseases. Large populations may amplify the risk of forest fires, timber loss, and impact human economic activities.
