The Spruce Bud Moth (Zeiraphera canadensis) is a moth of the Tortricidae family. The larvae feed mainly on Picea glauca but they have been found on other species of spruce and fir. While it is not a concern in natural stands, in spruce plantations in is considered a pest, as repeated years of defoliation leads to deformity in the crown, loss of stem form and lower productivity.
