Numerous species
Pest description and damage Identification is important as root weevil species differ in susceptibility to pesticides and may have different life cycles. Adults of most of the species are all females and capable of laying eggs after a period of feeding to mature their ovaries. Larvae, found around roots, are C-shaped, legless, and white, or slightly reddish, with tan heads, up to 0.5 inch in size. All species are quite similar in appearance and habits of feeding on root hairs, larger roots, and root crown. Adult weevils are dark colored night feeders, from 0.2 to 0.25 inch in length, that mostly remain in the soil or in debris at the base of the plant during the day, then climb up to feed on leaves at night. Look for ragged notches on the edges of leaves, or flower petals or dead tips of plants where weevils have girdled the twig.
