Metcalfa pruinosa (Say, 1830)

This flatid planthopper is found in North- and Central America and was accidentally introduced into southern Europe in 1979 (first record from Italy), where it is now considered a serious and polyphagous pest. Since 2009, it has been also reported from Korea. Among the many host plants, fruit trees, other trees and ornamentals are attacked.

The adult is 5-8 mm long and greyish brown with yellowish eyes. There are numerous light spots across the forewings which also have several dark marks near the base. The nymphs are covered with waxy filaments and reach a length of 4 mm.
