Sugarbeet Wireworm
Limonius californicus (Mannerheim)

Larvae are slender, cylindrical, up to 25 mm long, shiny, yellow to brown, hard-bodied "worms" with small legs. Usually their last segment is somewhat elongated with short, stout appendages on the end. Damage occurs as they tunnel in or feed on seeds, roots, seedlings, and tubers. Host plants: potatoes, beans, sugarbeets, corn, cereals, red clover.
