Thus, males are always haploid and females are diploid because females are produced from fertilized egg. ·          In some species such as Tenthredinidae, reproduction is alays parthenogenetically and males of this species are not known. Artificial parthenogenesis: ·          In normal conditions some eggs do not develop unless they are fertilized. ·          In such conditions, when ripe egg is induced artificially the development start
