Pryeria sinica
euonymus leaf notcher, euonymus defoliator moth
Pryeria sinica is a univoltine zygaenid moth native to East Asia, introduced to the United States in 2002 where it has established populations in Maryland and Virginia. The species is a specialist herbivore of Celastraceae, particularly Euonymus species, where larvae feed gregariously and create distinctive marginal notches on leaves. Adults are diurnal wasp mimics with clear wings and aposematic coloration. The species has been reported more recently in the United Kingdom.
