• Acanalonia conica

  Green Cone-headed Planthopper

  Acanalonia conica is a planthopper species native to North America that has established invasive populations across Europe since its first detection in Italy in 2003. Adults are bright green with a distinctive conical head and red eyes, while nymphs are brown with white waxy filaments. The species is univoltine, highly polyphagous, and produces abundant honeydew. In Europe, it has been observed forming denser populations than in its native range and is considered a potential agricultural pest.
