Pseudaonidia paeoniae
Peony Scale
Pseudaonidia paeoniae, commonly known as the Peony Scale, is a species of armored scale insect in the family Diaspididae. It is a specialized herbivore that feeds on peonies (Paeonia spp.), extracting plant fluids through piercing-sucking mouthparts. The species has been documented across multiple continents including Asia, Europe, and North America, likely distributed through the horticultural trade of its host plants. Like other armored scales, it produces a protective waxy covering (test) that shields the body from predators and environmental conditions.
