Pyromorpha dimidiata
Orange-patched Smoky Moth
Pyromorpha dimidiata is a leaf skeletonizer moth in the family Zygaenidae, native to eastern North America. Adults display distinctive orange and dark gray forewings with a pattern that resembles toxic net-winged beetles (Calopteron spp.) in a Müllerian mimicry complex. All life stages contain hydrogen cyanide, which the moth synthesizes independently rather than sequestering from host plants. The species is active primarily in spring and early summer.
