Histological changes in the fat body of the housefly during metamorphosis were studied, with special reference to the origin of pupal and adult fat body. After pupation, the larval fat body was disorganized and each cell floated freely within the abdominal cavity. Histolized fragments of larval tissues were phagositized by granulocytes which subsequently turned into spherule cells. The granulocytes localized under the epidermis were organized and formed the adult fat body at the middle pupal stage. The larval fat body cells, having phagositized the spherule cells and nucleic droplets, were broken down completely after the middle pupal stage. Cell materials of larval fat body were aggregated around the chromatin and formed the pupal fat body in the late pupal stage. Consequently, the evidence suggests that both the pupal and adult fat body are the tissues generated during metamorphosis. Furthermore, the granulocytes appear to play an important role in the formation of the fat body.
