This Quick scan was prompted by a request of an organisation to import Leucoma wiltshirei for research purposes. The organism is not known to be present in the EU. The only known host plant of L. wiltshirei is Quercus brantii. The climate in the south of the EU is probably suitable for establishment. The potential economic impact is assessed to be low. Q. brantii does not occur natively in the EU and is not commonly planted; it may be present locally.
