    Once considered a distinct species and felt to be exceedingly rare, "Papilio diaphora" is now believed to be a form or subspecies of P. xanthopleura, distinguished by yellow banding on the forewing; it is noted with increasing frequency as one travels east from Iquitos Peru along the Amazon. It is very local and spends much of its time in the canopy. Females almost never come down to the ground, but males may puddle in good numbers early in the morning before returning to the canopy (personal communication)
