According to the papers containing key for Taedia species, the first gate for identifying eastern species is whether its hind tibiae has long hairs that may be confused with the tibial spines. If yes, it is T. scrupea. If not, it may be other species that can be rather easily distinguished by appearance and color.

Unfortunately, T. scrupea has so many variations that it cannot be easily distinguished from other species. That's the problem. We need a magnification of hind tibiae or a more experienced expert. ^^
