The data on the egg hatchabillity, adult formation and F_1 fertility in interspecific hybrids of some Papilio species, produced by hand pairing method, show notable variations according to the combination. Differentiation indexes for all crossings were calculated from these data as a criterion for genetic distance to study the phylogenetic relationships of the species involved. The data suggest the existence of the following groups, each consisting of closely related species: black Papilio supergroup, Papilio memnon group, P. polytes group, P. bianor group, P. machaon group, P. xuthus group, P. demoleus group, P. glaucus group, P. troilus group, The differentiation index between very closely related species shows that speciation has been completed when F_2 fertility is reduced to some extent as in the case of Papilio polytes versus P. alphenor. Also, speciation may have been completed if random mating is genetically averted as in the case of Colias eurytheme versus C. philodice. An estimate of 1 milion years for a speciation may be induced from Papilio relations between the Philippines, the Okinawa Islands and the Asian Continent.
