Flatheaded borers

Buprestidae spp.

Adult borers are beetles that are often metallic (coppery, blue, black, or green), particularly on the lower surface and upper abdomen. Their bodies are flattened, elongated or oval, and typically have longitudinal grooves on the wing covers. The larvae are light colored and have a distinctive shape with a flattened enlargement just behind the tiny head.
Damage: Flatheaded borers attack aboveground portions of trees that have been previously injured by sunburn or other causes. Tunnels excavated beneath the bark by the borer larvae may cause a wet sappy area on the bark of the main trunk, which may later crack. Limbs or trees may be killed.
