The metamorphosis process of butterflies

Schematic diagram of butterfly metamorphosis process

Textual interpretation of the process of butterfly transformation

At the early stage of adult emergence, the pupal shell breaks between pupal wings, and the dorsal midline of the anterior, middle and posterior thoracic segments and the connecting line between the head and chest are broken at the same time. Appendices of the head (antenna and beak tube, etc.). ) and the front legs are extended first, and then the middle feet, hind feet and wings are pulled out. After the feet climb on something else, the body leaves the pupa shell immediately. Soft and shriveled fins will expand rapidly in 5~6 minutes. But at this time, the wing membrane is not dry and solid, and the wing body is still very soft and unable to fly. It must be 1~2 hours before you can fly high.
