The mountain pine beetle (Dendroctonus ponderosae) is a species of bark beetle native to the forests of western North America from Mexico to central British Columbia. It has a hard black exoskeleton, and measures approximately 5 millimetres (1⁄4 in), about the size of a grain of rice. In western North America, an outbreak of the beetle and its microbial associates affected wide areas of lodgepole pine forest, including more than 160,000 km2 (40 million acres) of forest in British Columbia.
