The Engelmann spruce weevil

The Engelmann spruce weevil causes widespread damage to many kinds of evergreen trees. These weevils are dark brown with a prominent hooked snout of the weevil. The adults overwinter in debris beneath trees, and in the spring they ascend the vertical stem at the top of the trunk to feed and mate. Trees will lose up to three years of height growth in six weeks of feeding. This harmful pest attacks at least 20 different species of trees including the Sitka, white, and Engelmann spruce, as well as, the Mugho pine and blue spruce. A classic sign that an evergreen tree is infested with the white pine weevil is the shepherd’s crook in the new expanding leader. This damage generally appears in late spring to mid-summer. The first sign of attack is the presence of drips of resin discharging from minute feeding holes in May – June.
