The neurohypophysis is only found in the dorsal region between the RPD and the PPD. The growth hormone cells do not differentiate in the PPD of the adenohypophysis, occupying 2/3 of the PPD until the larva is 5 days old. The other hormone-producing cells in the RPD and in the PT do not differetiate. In the 10-day old larva, the hormone-producing cells except the GH cells in the adenohypophysis do not differentiate. In 15-day old larva, the adrenocorticotropic hormone cells differentiate in the RPD and the other hormone-producing cells in the adenohypophysis do not differentiate. In the 30-day old larva, the all kinds of hormone-producing cells are formed in the adenlhypophysis.

It could display only when exposed to disturbance which causes the degradation of ecosystem however it is impacted by natural or nonnatural factors.
