Pest description and damage Species identification is important as root weevil species differ in susceptibility to pesticides and can 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. Larvae are rarely a problem in landscapes. Look for ragged notches on the edges of leaves, or flower petals or dead tips of plants where weevils have girdled the twig.
