Rheumaptera undulata/prunivorata – Scallop Shell Moth

Hodges # 7291 – 7292

Caterpillar foods: Black Cherry – R. prunivorata;  Alder, poplar, spirea, willow and possibly other plants – R. undulata (Wagner)

These two species are nearly indistinguishable as adults, but the caterpillars have quite different appearance and behaviors.  R. prunivorata is gregarious, has white sides and a black back, and can sometimes be a pest on Black Cherry.  It ties up and kills an entire shoot.  R. undulata caterpillars are solitary and have less striking coloration. (Wagner)
