California lilac (Ceanothus)-Root weevil

Numerous species

Pest description and damage Identification is important: species differ in susceptibility to pesticides. Adult weevils are dark colored, nocturnal beetles between 0.2 and 0.25 inch long, 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. The Larvae are rarely a significant problem in established landscapes.
