Que trouve-t-on à l'intérieur d'une chrysalide? - C'est pas sorcier

Well, first of all, you should know that the organs of the butterfly are already present in the caterpillar, but in the state of tiny swallows, here for the wings, there for the legs, for example. It is a hormone, that is to say, a substance produced by the animal that blocks the evolution of these swallows. So when the animal has transformed into a chrysalis and stops producing this hormone, well, there, the swallows begin to develop. The legs grow, the wings also, a second heart to feed the wings, the antennas also grow, as well as the animal's trunk, the mandibles disappear, other organs transform, it is the case of the eyes, which become much more powerful faceted eyes, it is also the case of the digestive system, which atrophies. The place is now occupied by the genital system, normal, the caterpillar spends its time eating, the butterfly must reproduce. Finally, the animal will give birth to its last skin, it comes out of the chrysalis and becomes a butterfly.
