A Brief Introduction:
Ostrinia furnacalis represents one of the two Ostrinia species in Taiwan and shares very similar wing pattern with the other species, O. scapulalis. Identification of the two species from wing pattern is difficult but that from male mesotibia is relatively easy. The former has normal-sized mesotibiae while the latter has expanding ones.
