First record of Corythucha arcuata in Slovakia - short communication.


In June 2018, the presence of one adult specimen and one egg cluster of the North-American oak lace bug Corythucha arcuata were recorded near the village of Mužla, close to the Danube River, in southern Slovakia. They were found on leaves of Quercus cerris growing in a mixed stand. In August 2018, other specimens (nymphs and adults) were observed on Quercus robur leaves, near Čičarovce, in eastern Slovakia. This is the first record of C. arcuata in our country. The oak lace bug probably reached us while invading from Hungary, where heavy infestation is reported from several parts of the country.
