Since the Pine Sawyer Beetle loves high altitudes and evergreens, the Rocky Mountains are the right place to call home.
Pine Sawyer Beetles are found in coniferous forests at elevations over 1,200 meters. Ponderosa Pine tree and Douglas Firs are preferred habitat. Active at dusk, adults can be seen flying near lights (males) or walking on logs or stumps. The pronotum ('shoulder' area) has spines on it and their armor-like wings are highly textured.
Females lay fertilized eggs in the bark of dead or decaying trees, stumps and logs. Larvae hatch and proceed bore through dead wood, feeding on the sap inside as well as the heartwood in the center. They emerge as adults in summer, leaving behind their tunnels and capsule-shaped exit holes.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Antennae: Beetles have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).
Thorax: Holds the three pairs of legs as well as vital internal organs.
Elytron: One of two wing cases on a Beetle that protects its wings (plural: elytra).
Wings: Appendages used for flying and kept under the elytra until needed.
