Papilio joannae

[Ron Gatrelle]

Anyone interested in a discussion of Papilio joanae (Missouri Ozark Black
Swallowtail)? Why has it been blacklisted from much of butterfly
literature? My discussions with the late Richard Heitzman (who
discovered/described this) is that he felt it was most closely related to P
bairdii or as some see it P. machaon bairdii. I know of no published
scientific paper in which joanae has been officially sunk into the machaon
complex of subspecies. It can be found in Heitzman's 1987 Butterflies and
Moths of Missouri.
