The large, copper eyes and sparkly eltyra of the Western Sculptured Pine Borer gleam in sunlight, but they are not the only special features on this beetle.
A large beetle, the Western Sculptured Pine Borer represents its genus in the western part of the continent. The profile of this beetle is compressed, giving it a flattened appearance. The gray and black wing coverings (elytra) have speckles of metallic shimmer. The black markings are slightly raised, as if sculpted out of the rest of the elytra. Its round eyes seem filled with copper and it rings around the outer edges, too. If startled, it flies away, making a lot of noise as it goes. It is in flight that one can catch a glimpse of its dazzling purple-blue, iridescent abdomen.
Adults feed on pine needles, but larvae feed on the wood inside. Females lay fertilized eggs on bark and the newly hatched larvae bore into the trunk, digging shallow tunnels in the wood. Most varieties of pine are used as host plants, but fir trees also suffice. Look for adults in coniferous forests.
