| Research Abstract |
Of the 12 papilionid butterflies inhabiting in Japan, 6 species were sexually dimorphic but 6 species were sexually monomorphic in the chemical composition of cuticular lipid of adults. Prior to copulation, male adults of Papilio xuthusand Papiliopolytesare found to show palpation behavior to mating partners using their forelegs. Electrophysiological measurements revealed that sensilla trichodea of the foreleg tarsi show gustatory responses to the cuticular lipid extracts from conspecific and heterospecific adults. These results strongly suggest that adults of papilionid butterflies use the cuticular lipid substances of mating partners for chemical cues of mate recognition.
