The wing covers are spotted with brown and white scales. White pine weevil eggs are small, pearly white and translucent.
Mature larvae are yellowish-white, legless grubs with brown heads.
This weevil infests other pines and spruces, especially Norway spruce. In mid June, infested branches begin to wilt. One or more of the top branches grow upward to replace the leader which results in a crooked or multiple trunk tree. Adults feed on the buds and bark to a limited extent. Adults overwinter in litter.
