What substance do adult and young lacebugs suck from plants?

Adult and young lacebugs primarily feed on the sap of plants. They use their specialized mouthparts to pierce through the plant tissue and extract the nutrient-rich sap. This feeding behavior can lead to various plant health issues, including leaf discoloration, reduced vigor, and in some cases, the even death of the plant if the infestation is severe.

While other options like pollen, leaf tissue, and roots may be associated with different insect feeding behaviors or plant interactions, lacebugs specifically target the sap because it provides essential nutrients necessary for their growth and reproduction. Their feeding on the sap can also create stress on the plants, making them more susceptible to diseases. Understanding this feeding behavior is crucial for effective pest management strategies aimed at controlling lacebug populations and minimizing their impact on plants.
