Abstract: | Abstract. 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. |
