Definition
A of woodboring longhorn () and the sole member of the Hylotrupes. Native to Europe and now , it is among the most economically significant pests of seasoned softwood timber in structural lumber, causing extensive damage through larval tunneling in pine, spruce, and fir. are recognized by their elongated, slightly flattened bodies (8–20 mm), grey-brown coloration with two whitish pubescent bands on the , and long, serrate . The species has an exceptionally long (3–10 years, typically 5–6), with larvae boring galleries that compromise wood integrity long before holes become visible.

Usage Notes
vary regionally; 'Italian ' in South Africa refers to historical import , not origin. The is distinguished from other cerambycids by its preference for seasoned rather than green wood. Larval galleries run predominantly with the grain, unlike the cross-grain tunnels of Anobium punctatum (). are often cryptic for years, requiring acoustic detection or core sampling for early identification. Taxonomic authorities list Linnaeus, 1758 as the original combination (Cerambyx bajulus).
