White pine weevil


White pine weevil- Identification

White pine weevil is more recognizable by its damage than by the beetle itself.

Look for pitch flowing from feeding wounds on terminal shoots in spring. The new growth appears stunted and finally wilts.

In addition, look for pupal chambers or "chip cocoons" made by the larvae along the main stem.
