Billbugs are common lawn pests. They are a type of weevil. Adult billbugs feed on above-ground parts of grasses. They are about one-half inch long and can be yellow, reddish brown, or black. They are characterized by their long, elephant like snout, or bill. Their snouts are strong mandibles that allow for easy chewing. The mature billbug will feed on grass and females will chew holes in stems to lay her eggs. Larvae look like wiggling grains of rice. They feed on the grass roots below the soil. Larvae cause more damage than adult billbugs.
