Which type of beetle larva is associated with feeding on hardwoods?

The True Powder Post Beetle larva is known for its association with hardwood trees, where it feeds on the wood. These larvae have specialized mouthparts that are adept at breaking down the cellulose found in hardwood, allowing them to thrive in this type of environment. Often found in seasoned or dried wood, the damage they cause can be quite significant, as they create small exit holes in the wood surface once they emerge as adult beetles.

In contrast, while other insects listed may interact with wood or wood structures, they do not specifically focus on hardwoods like the True Powder Post Beetle. Dampwood termites primarily infest damp or decaying wood rather than hardwoods specifically. The Lead Cable Borer is more associated with feeding on cables and electrical equipment rather than wood materials. The Black Polycaon Beetle, while it may interact with various materials, is not primarily known for feeding on hardwoods.
