Thanks for request. Thre are eggs of Corythucha arcuata, commonly known as the oak lace bug, on oak leaves. Is a species of true bug belonging to the family Tingidae. It is known for its distinctive lace-like appearance on the leaves of oak trees, caused by its feeding activity. This insect can cause damage to oak trees by sucking sap from the leaves, leading to yellowing, wilting, and premature leaf drop. Best regards M. Zubrik
