Zhurov et al. paper

According to the paper, Copidosoma develops much differently than the Fruit fly.  This is due to Copidosoma using regulatory development, which is the same mechanism by which vertebrates develop.  This type of development is characterized by conditional specification resulting in tissues developing due to induction by neighboring tissues.  One Copidosoma egg gives rise to thousands of embryos and the VASA protein defines the germ line cells of reproducing individuals.  The ablation of one cell from a Copidosoma embryo (only if it is not the VASA containing cell) still results in formation of a complete larva. The Fruit fly, on the other hand, uses mosaic development characterized by syncytial specification resulting in reliance on maternal determinants to signal cell differentiation.  The ablation of one cell from a fruit fly embryo at the two-cell stage would result in only half a larva.
