What is the life span of silkworm moths?

Silkworm moths live for 2-8 days, and after mating for 3-4 hours, females can give birth to fertilized eggs, while silkworm moths (adults) leave offspring and will die soon. The eggs laid by silkworm moths → hatch silkworms → pupate → moths will complete the cycle of a new generation, which is the life history of silkworms.

Both male and female moths have white scales on their body surfaces, with a body length of 1.6 ~ 2.3 cm and a wing spread of 3.9 ~ 4.3 cm. The head is smaller. Compound eye 1 yes, black, semicircular, with degenerated mouthparts and thin lower lip. Antenna 1 pair, pinnate, thick at the bottom and thin at the end.

The antenna of the female moth is gray and short, while the antenna of the male moth is black and longer than that of the female moth. The anterior thoracic segment is anastomosed with the middle thoracic segment. There are two pairs of wings, both covered with white scales. The front wing is located in the middle chest, triangular and large, with three light and dark stripes. The hind wings are born in the back chest, smaller and slightly round, with two dark parallel lines.

Extended data:

The larvae of silkworm moths are called silkworms. Eating mulberry leaves before pupation spits out a lot of silk as cocoon, which is an important textile raw material. Also known as "silkworm", silkworm is one of the economic insects that feed on mulberry leaves and cocoon.

Silkworms originated in China and were domesticated by primitive silkworms living on mulberry trees in ancient times. It is homologous to the wild silkworm that eats mulberry in China today, and has 28 pairs of chromosomes. The development temperature of silkworm is 7-40℃, and the optimum feeding temperature is 20-30℃, which is mainly distributed in temperate, subtropical and tropical regions.

Silkworm is a completely metamorphosed insect, which has to go through four stages of development with completely different morphology and physiological functions: egg, larva, pupa and adult.
