Which of the following pests is known for sucking out plant juices?

Lacebugs are known for sucking out plant juices due to their specialized mouthparts designed for piercing plant tissues. They primarily feed on the underside of leaves, extracting sap and causing damage that can lead to discoloration, stippling, and even leaf drop. This feeding behavior can significantly weaken the plant and affect its overall health, making lacebugs particularly harmful in gardens and landscapes.

In contrast, caterpillars, grasshoppers, and cutworms primarily engage in different types of feeding behaviors. Caterpillars are larvae that feed on leaves, often chewing them rather than sucking. Grasshoppers consume a wide variety of plant material by chewing as well. Cutworms typically feed at the base of plants, cutting stems and eating foliage, rather than sucking juices from within the leaves. This distinction in feeding habits highlights why lacebugs are the correct choice for the question about pests that suck plant juices.
