The Mountain Pine Beetle (MPB) is an invasive species that is native to the western states and Canada, and is especially abundant in Colorado. They infest pine trees, particularly ponderosa, lodgepole, Scotch and limber, by tunneling under the bark in larger living trees, mating and laying eggs. The larvae spend the winter under the bark and transform into pupae in June and July. The MPB then produces bluestain fungi that aids in killing the tree...Figure 1.
