Harrisina coracina
(Clemens, 1861)
Harrisina coracina is a leaf skeletonizer in the Zygaenidae. The was originally described by Clemens in 1861 under the name Aglaope coracina. It is one of several species in the Harrisina, which are known for their distinctive larval feeding that produces skeletonized leaf damage. Records of this species were historically limited to Texas, though observations have expanded its known range.
