Hemlock (Tsuga)-Root weevil

Many species

Pest description and damage Species identification is important as root weevil species differ in susceptibility to pesticides and have different life cycles. Adult weevils are dark colored, nocturnal beetles from 0.2 to 0.25 inch in length with a snout (rostrum) and elbowed antennae. Look for ragged notches on the edges of needles. Tips may die beyond the point where weevils have girdled the twig. C-shaped white larvae may be a problem in forestry seedlings.
