Pest description and damage Identification is important as root weevil species differ in susceptibility to pesticides. Adult weevils are small dark nocturnal beetles with a snout (rostrum) and elbowed antennae. Look for ragged notches on the edges of leaves, or flower petals. Larvae are C-shaped, legless, and white, sometimes reddish, with tan heads, up to 0.5 inch in size. Larvae rarely cause significant root girdling damage in established landscapes.
