Beetles, Pacific Northwest
Both the larvae and adults live on and in dead trees and under the bark on logs.
Some species of Metallic Wood Boring Beetles will attack living trees or newly cut logs. Other species occur on the leaves of trees and shrubs or are leaf miners. These beetles will fly when they are alarmed.
Some tropical species can grow much bigger with some reaching 100 mm in length. These beetles are mostly metallic colored and often coppery, green, blue or black with the front wings often having a distinct sculptured surface.
The body is hard, compact and often flattened.
