What is a characteristic of the larval galleries of the Roundheaded borer?

The characteristic of the larval galleries of the Roundheaded borer being irregular and packed with frass is accurate due to the feeding habits of the larvae. As these larvae tunnel through the wood, they create galleries that are not uniform in shape or direction; instead, they exhibit an irregular pattern as they navigate the wood. Additionally, the presence of frass—wood shavings and excrement—accumulates within these galleries, further indicating that the larvae are actively feeding and creating waste as they move through the host material. This accumulation of frass is a key identifier when assessing the damage caused by Roundheaded borers, setting it apart from the characteristics of galleries formed by other pests. Understanding this behavior aids in identification and management strategies for pest control professionals dealing with wood-boring insects.
