• Fiorinia

  Fiorinia is a genus of armored scale insects (family Diaspididae) comprising approximately 70 species. The genus is characterized by pupillarial development, where the adult female remains enclosed within the second-instar exuviae. Species are predominantly distributed in tropical and subtropical Asia and the Pacific Islands, though several have become invasive pests globally through trade in ornamental plants. Notable invasive species include F. externa (elongate hemlock scale), F. fioriniae (palm fiorinia scale), F. phantasma (phantasma scale), and F. theae (tea scale).
