Colaspis brunnea, the grape colaspis, is a species of leaf beetle from North America. It mainly occurs in the eastern United States. It is a pest of crop such as corn and soybeans, but damage by it has not been documented as economically significant. It is univoltine, and overwinters in the soil as larvae.[1]
The adults are brown-colored (brunnea is Latin for brown) and are around 5 mm in length. The elytra have a series of parallel rows of "puncture" marks. The larvae are scarabaeiform grub with white-grey bodies and orange head capsules, and are between 5 and 6.5 mm long at the 10th instar.
