White Pine Weevil
COMMON INSECT PESTS
The larvae of white pine weevil feed extensively on the needles and can kill the tops of fir, spruce and pine trees. They emerge in early spring after wintering under the host trees and adults will quickly begin to feed on the needle and then begin egg production, laying as many as a hundred eggs each.
Symptoms: Visible signs of resin oozing out of small holes chewed by the female weevil on the terminal branches. The larvae feed just below the bark.
