Pest description and crop damage The linden aphid is green with black lateral stripes. The aphid feed in colonies on the undersides of leaves. Feeding damage to the plant is usually minor, although some leaf and shoot distortion can occur if populations are high. Aphid also produce honeydew, a sweet, sticky secretion that collects on plant tissues and encourages growth of a black sooty mold. This can interfere with photosynthesis of the plant.
