Corythucha ciliata, the sycamore lace bug, is a species of lace bug in the familyTingidae that is associated with sycamore trees. It's also known as the plane lace bug due to its association with the London plane (Platanus × hispanica).[2]
It originates in the New World, but has been introduced and has spread in Europe. It is a small, whitish insect and feeds on the underside of the leaves, sucking sap.
There are reports in Europe of C. cilata landing on people and biting them. Reports from Italy,[3] France[4] and Romania[5] indicate that some people experience adverse reactions, e.g., dermatosis.
