A flash of metallic colors on the abdomen of the Large Flathead Pine Heartwood Borer can be seen when they take flight.
The long common name of this wood borer aptly describes much about it. It prefers coniferous forests and, particularly, the pine trees in them. Adult beetles usually breeds on dead trees and in stumps. Sometimes, however, it breeds in living pines. The larvae of the Large Flathead Pine Heartwood Borer hatch and bore, or dig, their way through the heartwood of the tree. This tunneling tends to destroy the tree's cambium tissue through which water and nutrients flow and can starve the tree to death if it is infested.
When the Large Flathead Pine Heartwood Borer adult flies, it reveals a bright abdomen (belly) that has a blue-green metallic sheen to it. This flash of color is not visible when the beetle's wings are closed. They are known to make a noise as they fly, which can help observers locate them if they're in a quiet forest.
The beetle can be found most often in the eastern part of the continent, from Canada to Florida, but its range has spread to any region that grows conifers. This means it can also be found coast-to-coast; in California and other states not originally thought to be its range.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Antennae: Beetles have a pair of antennae on the head used as sensors.
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.
