Though the adult beetle is beautiful to behold, its larvae are notorious for tunneling under tree bark, disrupting the tree's ability to move water and nutrients. This particular species favors the Eastern White Pine. Large adults can blend in with trunks thanks to long and short black lines and a bumpy texture on the wing coverings. Females lay eggs in the bark, and larvae chew their way deeper into the tree. Once at the cambium layer, the larvae meander through the tissue, breaking the lines of transportation between the roots and needles of the tree. It can take years before the larvae emerge from the tree as adults.
Look for adult Chalcophora fortis beetles in coniferous forests. Sometimes frass, a mix of sawdust and beetle feces, can be found on trunks that have the larvae inside them.

Antennae: Beetles have a pair of antennae on the head used for sensing.
Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).
Thorax: Holds the three pairs of legs as well as vital internal organs.
Elytron: One of two wing cases on a Beetle that protects its wings (plural: elytra).
Wings: Appendages used for flying and kept under the elytra until needed.
Abdomen: Houses organs related to circulation, reproduction, and excretion.
Legs: Beetles have three pairs of legs located at the thorax, numbering six legs in all.
