    Pine Sawyer Beetle - (Ergates spiculatus)

    Since the Pine Sawyer Beetle loves high altitudes and evergreens, the Rocky Mountains are the right place to call home.

    Staff Writer (1/27/2014): 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.
