• Metcalfa

  Metcalfa is a genus of planthoppers in the family Flatidae, tribe Nephesini, native to North and Central America. The genus contains at least five described species, with Metcalfa pruinosa (citrus flatid planthopper) being the most economically significant due to its invasive spread to Europe and Asia. Adults are small, ranging 5.5–8 mm in length with a waxy, often bluish or grayish appearance. The genus is characterized by forewings with parallel cross-veins along the costal margin, distinguishing it from related families.
