There are two species of COLASPIS in Louisiana rice: Colaspis brunnae and Colaspis louisianae. This pest can be found damaging fields of dry-seeded rice in a soybean-rice rotation. Colaspis will complete a single generation in soybeans, lespedeza or pasture. The larvae of colaspis will overwinter in the soil. The larvae will feed on the roots of a plant, such as rice, when it is planted into a field infested with the developing insect. The larvae will pupate in the soil and emerge as adults. Adults are oval in shape and about ¼-inch in length. They are a light golden color with white/gold stripes down their back and long antennae. Adults do not lay eggs on rice, but will most likely travel to a near soybean field.
