Coordinator notes: From bugguide.net: this is a "member of the Apodemia mormo complex or "superspecies", of which members are all considered as a single variable species by some authors, while other authors recognize varied numbers of distinct species. Certain types that look different may coexist in the same locations, yet remain distinct, which implies that in those areas there are at least two species. Relationships between various populations are still being sorted out.
A. duryi appears to be just a southern subspecies of A. mejicanus as evidenced by intermediate specimens found where they meet, but this question needs more study." SAT
