Papilio nandina  (female) (orange form)
 
Extremely Rare Natural Hybrid Papilio nandina, a probable hybrid between Papilio dardanus and Papilio phorcas   Hybrids bred in the laboratory between Papilio dardanus Brown and Papilio phorcas Cramer resulted in male butterflies similar to the two naturally occurring males described as P.nandina Rothschild & Jordan. A single female hybrid insect resembling the female parent was also bred. Male hybrids were also obtained between P.dardanus and P.demodocus/demoleus but not between P.dardanus and P.constantinus.

The phylogenetic relationships of dardanus and phorcas are discussed, and reasons given for preferring the older hypothesis that male‐like females are primitive rather than that they represent the most specialized forms. Further information on this point would be forthcoming if backcrosses and F2 s could be obtained.  A natural hybrid between P dardanus and P phorcas. Most hybrids tend to be sterile and are therefore rather rare; I am not sure whether it is known if nandina can reproduce or not. xtremely Rare Natural Hybrid Papilio nandina ORANGE form female!!!
