Colorado Potato Beetles

Colorado potato beetle (CPB) feeds exclusively on solanaceous crops and weeds, and can be a significant pest of potatoes, tomatoes and eggplant. Adult beetles have characteristic cream and black stripes across the back. Females deposit eggs in clusters on the underside of leaves. The eggs are orange and each mass will contain between 20-45 eggs. CPB larvae are crimson in the early instars with black legs and two rows of black spots on the sides of their body. Large larvae are orange and appear bloated and humpbacked. Pupae are located in the soil.
