There are over 700 species of Buprestidae in North America. Buprestid beetles are similar to click beetles, but without the "click" mechanism or the sharp projections at the corners of the pronotum. Buprestid larvae are called "flatheaded borers". They live in bark, wood, and sometimes the leaves of various plants. Currently, the Emerald Ash Borer is the Buprestid of the moment here in the American Midwest.

Identifying characteristics for the family Buprestidae include: First abdominal sternite entire, not divided by hind coxae (suborder Polyphaga), Hard bodied, elongate-slender to elongate-robust beetles, ranging from 2 to 40 mm in length. Many species metallic or bronzed in appearance, especially on the ventral surface. Antennae usually short and sawtoothed.

Order Coleoptera: Beetles are the dominant form of life on earth: one of every five living species is a beetle. Coleoptera is the largest order in the animal kingdom, containing a third of all insect species. There are about 400,000 known species worldwide, ~30,000 of which live in North America.  Beetles live in nearly every habitat, and for every kind of food, there's probably a beetle species that eats it.
Beetles first appeared during the lower Permian period, about 270 mya
