In Drosophila puparium is a cuticular mould of external structures formed by the larval cells and can, therefore, preserve traces of developmental defects which appeared in embryogenesis. In this way ontogenetic relationship between embryonic defects and developmental defects in adult individuals can be established. The normal pattern of segmentation in puparia of Drosophila melanogaster was established by comparing segmentation defects in adult flies and corresponding puparia. Boundaries of segment and compartments have been determined, imaginal rudiments of abdominal segments (nests of histoblasts) and rudiments of trachea have been localized on puparia.
在果蝇中，蛹壳是由幼虫细胞形成的外部结构的角质模具，因此能够保留胚胎发育过程中出现的发育缺陷痕迹。通过这种方式，可以建立胚胎缺陷与成年个体发育缺陷之间的个体发育关系。通过比较成年果蝇和相应蛹壳中的节段缺陷，确定了黑腹果蝇蛹壳的正常节段模式。节段和隔室的边界已被确定，腹部节段的成虫芽（组织母细胞巢）和气管的芽在蛹壳上已被定位。
