Some animals cease to undergo this process when they reach the imago stage.
In 1999, Phlippen et al. showed that this process is accompanied by a massive release of cardioactive peptide, which may account for changes in behavior during this process. Wigglesworth linked the circulatory systems of two animals to prove that this process is controlled by a circulating hormone, now known to be the steroid 20E, though this process is initiated by (*) prothoracicotropic hormone. This process is preceded by apolysis, and an organism undergoing it becomes teneral and leaves an exuvium. Some animals cease to undergo this process when they reach the imago stage. Occurring after each instar, for 10 points, name this process by which an arthropod sheds its exoskeleton.
