There are several pairs of legs on the head of the silkworm moth

The silkworm moth has a total of eight pairs of legs. The adult worm of the silkworm moth is covered with white scales and hairs all over its body. The head is small, compound eyes are paired, the antennae are feathery, the mouthparts are degenerated, and they cannot eat food.

The thorax has three pairs of legs and two pairs of wings, and the ability to fly has deteriorated due to long-term captivity. Male moths are smaller in body than female moths and have long pinnate branches on their antennae. There are five pairs of feet in the abdomen, the first four pairs can make the body forward, and the last pair is called the tail foot, which fixes the body to the mulberry leaves.

Silkworm moth adults are medium-sized. Stout. No beak, no feeding.

Both the female and male antennae are ctenoid. The feet have wool. The larvae have a smooth body, a short horn process on the back of the 8th abdominal segment, and the larvae spin silk and form cocoons before pupation.

Silkworm is the world's silkworm, native to China, has spread all over the world. Domesticated from the wild to domestic feeding, various places have been bred and differentiated into many varieties, the silk color is white and yellow, and the host is mulberry.

Uses:

Silkworm moth is a by-product of silkworm seed farm production, especially after the male moth is mated, it is only used for feed, which is a great waste. According to the survey, its oil content is as high as the pupa is unreachable, and its protein richness is also considerable, so it can be used to extract moth oil, and then use the defatted silkworm moth to make liquid monosodium glutamate, which not only turns waste into use, but also can be used for multiple purposes.

Silkworm moths have a total of eight pairs of legs, which are distributed on the thorax and abdomen. Among them, the thorax has three pairs of feet and two pairs of wings, which can support and fix the body. There are five pairs of legs in the abdomen, the first four pairs can make the body forward, and the last pair is called the tail foot, so that the body is fixed to the mulberry leaves.

The appearance is different: the female moth is larger, with an extremely swollen abdomen and relatively small wings; Male moths are smaller in size, with a thinner belly and relatively large wings.

The physiological structure is different: the female moth has an oviposition valve in its physiological structure, and there are two pale yellow egg-shaped perfume sacs on the tail; Male moths have a penis on their physiological structure.

Mobility is different: female moths are slow and almost incapacitated; Male moths have relatively large wings and crawl quickly, and their wings can vibrate and fly quickly.

Generally, after 3 to 4 hours of mating between the female moth and the male moth, the female moth can lay fertilized eggs. Silkworm moths (adults) leave offspring and die soon after. The eggs laid by the silkworm moth will be incubated and then pupated and finally turned into a moth, and the cycle of a new generation will be completed. This is the life history of silkworms.

It is understood that silkworm moth can refer to the general name of the insects of the silkworm moth family of the whole Lepidoptera with the order Lepidoptera, the general family of silkworm moths, and there are more than 100 species. Most of them can fly, and the common ones are wild silkworms, mulberry cockroaches, etc.

Silkworm moths can also refer to the adult worms of silkworms, their ancestors were able to fly, but now they have degraded and cannot fly. As a result of their long-term domestication by humans, they have lost the ability to fly due to their large bodies and small pairs of wings, and it is important to note that flapping their wings does not mean that they are flying.

The silkworm moth has a pair of antennae on its head, the antennae are feathery, and the antennae have long pinnate branches. The antennae of the female moth are gray and shorter, and the male is black and longer than the female. The anterior and midthoracic segments are anastomosed.

Wings 2 pairs, both covered with white scales, forewings located in the midthorax, triangular, larger, with 3 pale dark transverse stripes, hindwings born in hind thorax, smaller, slightly rounded, with 2 darker parallel lines. 3 pairs of feet, 5 tarsal segments, with 1 pair of black-brown claws, with cotton-like hairs.

Females have a fat abdomen with a blunt and rounded end, while males have a narrow abdomen with a slightly pointed end. The larvae are silkworms, cylindrical, grayish-white, with dark markings, all sparse yellow-brown short hairs, composed of 13 links except the head, the head is small and hard, with single eyes, antennae, lips, jaws and spinning tubes.

Summary. A male silkworm moth can be matched with two to three female silkworm moths, it should be noted that although the male silkworm moth can mate many times, only the first time is of relatively high quality, so it is best to use it only once if possible, usually silkworm moths will lay eggs within 24 hours after mating, the eggs are pale yellow when they are just laid, after 1-2 days will become red bean color, and after a few days will turn purple, after which they will hatch young silkworms.

A male silkworm moth can be matched with two to three land fighting friends only female silkworm moth, it should be noted that although the male silkworm moth can mate many times, but only the first time the quality is relatively high, so it is best to use it only once if possible, usually the silkworm moth will lay eggs within 24 hours after mating, the eggs are pale yellow when they are just laid, after 1-2 days will become red bean color, and after a few days will turn purple, and then they will hatch and stare at the young silkworms. Early locust.

Silkworm moth is fertilized in the body, the female silkworm moth has more eggs, can mate with multiple male silkworm moths, I have also seen a male silkworm moth and multiple female silkworm moths mating situation, when the female silkworm returns to the lack of moth eggs, consumes the energy in its own body, organ degradation will die, the same male silkworm after mating, also consumes the energy in their own body to leak this argument will die, the death of the silkworm moth completes the task of the organism itself, and continues the next generation.
