• Metcalfa pruinosa

  Citrus Flatid Planthopper

  Metcalfa pruinosa is a polyphagous planthopper native to North America that has become a significant invasive pest across Europe, Asia, and other regions. Adults measure 5.5–8 mm in length and are covered in a distinctive bluish-white waxy coating. The species produces one generation per year, with eggs overwintering in bark crevices. It feeds gregariously on plant sap, excreting honeydew that promotes sooty mold growth and causes direct damage to crops and ornamentals. First described by Thomas Say in 1830, it has spread to over 20 countries and is known to attack more than 300 plant species.
