Spruce Engraver

Scolytus piceae is a in the , Scolytinae, commonly known as the Spruce Engraver. It is a primary phloem-feeding specializing on spruce trees, with documented associations with Engelmann spruce and spruce in northern Idaho. The species constructs galleries in the phloem tissue of trees where develop.
