Bark beetles, family Scolytidae, are common pests of conifers and some attack broadleaf trees. The most common species infesting pines in California are the western pine beetle (Dendroctonus brevicomis), engraver beetles (Ips spp.), and the red turpentine beetle (Dendroctonus valens). The species of tree attacked and the location of damage on the bark help in identifying the bark beetle species present.
