barnacle scale, barnacle wax scale
Ceroplastes cirripediformis, commonly known as the barnacle scale or barnacle wax scale, is a soft scale insect (Hemiptera: Coccidae) recognized for its distinctive waxy covering that resembles a small barnacle. It is a destructive invasive pest with a broad host range spanning numerous plant families. The species has expanded its range globally through human-mediated transport and climate change, with established populations across North America, South America, Europe, Asia, Africa, and Oceania. Females reproduce parthenogenetically, producing up to a thousand eggs annually without observed males in wild populations.
