The White-spotted Sawyer is a large, black longhorned beetle with a single white spot on its scutellum and variable white flecks across its elytra; males have antennae twice their body length. It is a major secondary decomposer of recently dead conifers after fire or storm events. The rasping sound made by larvae chewing through sapwood is audible at a distance.
