Remarks
There is no taxonomic distinction of this form of the Black Swallowtail, but they have been put under their own heading so that it is easier to find them.

This is a rare color form in this subspecies, but it can turn up most anywhere. It does seem to be marginally more common in the Southwest (Arizona, New Mexico, Texas, northern Mexico), perhaps because these places are geographically closer to subspecies coloro and other Mexican subspecies that commonly exibit the yellow color form.
