In order to clarify the fecundity and the number of eggs actually deposited of the yellowswallowtail butterflies, Papilio xuthus and P machaon, females were captured in the wild and dissectedForewing length was not correlated with age in any of the two species　Multiple matings suggested byspermatophore counts were found for P xuthus but not for P machaon in both spring and summergenerations　Eggs in the ovaries were classified into three categories according to their degree ofmaturation　The fecundity, which was a total number of eggs. was 500-600 eggs irrespective ofgeneration and species　The small body size of individuals belonging to the spnng generation seemed toaffect not the fecundity but the number and the size of mature eggs in the abdomen　Oviposition in thespring generation of P xuthus took place mainly at noon but that of the summer generation in themorning　Considering the oviposition period of both species. the number of eggs deposited in eachgeneration in each species was about 300 eggs, which was about a half of the fecundity
