How to identify Mountain Pine Beetle
Adult beetles are about 5 mm long and begin as a light creamy tan color, turning black when they mature.
Infected trees have red needles at the crown.
Sawdust collects at the base of infected trees from larvae feeding.
Larvae are legless grubs with red-brown heads and are found under the bark.
Beetles transfer a fungus to the tree that stains the sapwood blue.
