The adult of white pine weevil is a small rust-colored weevil with a long snout-like beak. The larva is white with a distinct brown head, lives beneath the bark.
Both adult and larva feed the terminal buds of the leader tree but most damage is done by larvae generally in spring. The first symptom of weevil attack is resin oozing from feeding punctures. The presence of the insect is easily detected by the dropping, wilted appearance of the current year’s leader, which resembles a shepherd’s crook.
