What will silkworm chrysalis become?

When the temperature of silkworm chrysalis gets warmer, it will become a silkworm moth. The common ones are silkworm and tussah.

Silkworm moth:

After eclosion, adults spit out alkaline intestinal juice to moisten and loosen the cocoon layer at the head end, and use chest and feet to open the cocoon silk and drill out from the cocoon. The wings are initially soft and folded, and spread out as the moth body dries. The whole body is covered with white scales, with a pair of compound eyes and a pair of comb-shaped antennae with touch and smell on both sides of the head, and the mouthparts have degenerated. There are one pair of chest feet on the ventral surface of the front, middle and back thoracic segments, and one pair of wings on the dorsal surface of the middle and back thoracic segments. There are 7 female moths and 8 male moths in the abdomen. The external genitalia of male moth changed from the 9th and 1th abdominal nodes of larvae, and that of female moth changed from the 8th, 9th and 1th abdominal nodes. When mating, the female moth extends out of the ovipositor, and the sex pheromone (bombyx mori alcohol and bombyx mori aldehyde) is released by the lure gland to lure the male moth, and the fertilized egg can be produced after mating for 1.5-2 hours. A female moth lays about 4 ~ 7 eggs, most of which are laid on the day of emergence and end on the third day. Adults don't eat, and they die naturally after about 1 days of mating and spawning.

ANTHERAEA pernyi moth:

After the pupa is exposed to temperature, it emerges into a moth in the cocoon, spits out alkaline solution to soften sericin in the cocoon layer at the cocoon hole, and then drills out from the cocoon hole. The moth is 3 ~ 5 cm long, and the female moth is slightly larger, with wings spread 14 ~ 16 cm, grayish brown or orange yellow, and the whole body is covered with scales. There are 1 pair of membranous eye-shaped markings on the front and rear wings, and the markings are surrounded by black, red, blue and white stripes.
