These beetles are separated into subfamilies, divided into several tribes consisting of genera.
Physical Description and Identification
Size: 0.12 to 3.15 in (0.3-8 cm); the average is 0.79 in (2 cm)
Color:Varied; all beetles in this family have a metallic sheen on their elytra, giving them an iridescent appearance.
Other Characteristic Features:They are generally cylindrical or ovoid.
Nicknamed “flatheaded borers”, the larvae are cream-colored with an enlarged head.
Pupation occurs inside the host plant, within chambers excavated during the larval stage.
Females lay their eggs on the surface of the host plant so that on hatching, the larvae can begin burrowing into the wood.

Identifying the Damage Caused by Them
Some of these beetles, like the emerald ash borer, can cause massive damage to trees by chewing on their host plants’ roots, stems, or leaves. This can lead to considerable losses to orchards and crops.
