Corythucha arcuata, the oak lace bug, is a species of Tingidae that is a pest of oaks.

It is native to the New World, and was first observed in Europe in 2000.

[2] A decade after its introduction to Europe, it began to spread rapidly, and has now become a major invasive pest in over 20 EU countries, where it forms large infestations on several oak species, and often does considerable damage, such that negative long-term effects on oak health and survival are expected.

[3][4] As of 2023, prospects for control of this invasive pest were considered poor, with projections that a continual spread across Europe is inevitable unless control can be achieved.

[3] While there is at least one potential biological control agent known from its native range in the United States (an egg parasitoid mymarid wasp[5]), there are no known predators or parasites in Europe.
