First report of the Nearctic planthopper Metcalfa pruinosa (Say, 1830) in Poland, its current status and potential threats (Hemiptera: Fulgoromorpha: Flatidae)

Metcalfa pruinosa(Say, 1830) was recorded for the first time in Poland, in the city of Warsaw. This Nearctic species of the Flatidae family was introduced into Europe in the late 1970s and has expanded its range ever since. We provide data on the first record as well as briefly characterize the insect in terms of its diagnostic features, biology and potential harm to agriculture and the environment.
