CATDOLL : CATDOLL: How do centipedes lay eggs?

1. How do centipedes lay eggs?

The reproduction process of centipedes

The reproduction process of centipedes includes mating, laying eggs, and hatching.

(1) Mating: Sexually mature centipedes will show signs of estrus and courtship. At first, the male centipede will move extremely restlessly, constantly shaking its antennae, crawling here and there, stopping and starting. When it smells the scent of the female centipede, it will immediately crawl towards the female centipede. The female centipede will start to crawl around, and soon the male centipede will crawl onto the back of the female centipede and immediately insert its reproductive limbs into the female centipede's reproductive hole. After a slight vibration, it will slowly inject semen, which takes 2 to 5 minutes. Mating takes place between 8 pm and 4 am, and generally does not occur at other times.

After mating, the male centipede will soon die due to exhaustion.

Pregnant centipedes have the habit of eating a lot and storing nutrients. Therefore, they should be fed a sufficient amount of high-nutrition mixed feed at this time to make the centipedes full and well fed, so as to lay more eggs and improve the hatching rate. At the same time, do not turn over their nests to avoid scaring the centipedes and affecting egg laying and hatching.

(2) Egg laying: After mating, the sperm and egg combine to form a fertilized egg, which develops in the centipede's body for about 30 days and matures, and soon after, the centipede begins laying eggs.

Behavior before laying eggs: The pregnant centipede's abdomen is expanding due to the maturation of the fertilized eggs, making it difficult to move. Later, the entrance of its nest is blocked with soil, and it does not eat, drink, or move around. Then the centipede lays eggs in its nest. At this time, you must not disturb it, let alone open its nest to peek, otherwise, the centipede will eat all the eggs it lays.

When centipedes lay eggs, their bodies are often bent into an S shape, with their antennae hanging in the air and tilted forward and upward, their legs lying flat on the breeding soil, their tail segments resting on the back plate in the middle of their bodies, and their tail legs sticking up high. At this time, the genital opening expands and contracts regularly, while the soft skin is turned over, and the eggs are discharged one by one and fall on the 8th to 9th back plate. After 2 to 3 hours of egg laying, the centipedes' antennae are no longer hanging in the air, and their tail legs are no longer sticking up. Then they cleverly turn their bodies sideways, and use the ventral surface of their bodies and legs to protect the egg mass, so that it is completely suspended in the air and hatches without contact with the breeding soil.

A centipede lays 40 to 70 eggs each time, with an average of 50 eggs. The fertilized eggs are golden yellow (unfertilized eggs are white), transparent, oval, and the size of sorghum grains. The surface of the eggs is sticky and the eggs often stick together. The egg membrane is elastic to protect the eggs from damage.

(3) Incubation: After laying eggs, the centipede holds the egg mass to incubate them. During this period, it does not eat, drink, or move. It uses its trunk to drive away insects that approach it, and often secretes saliva and licks the egg mass with its mandibles to keep the eggs clean and prevent the invasion of pests and diseases.

The incubation period is about 40 days. During this period, centipedes do not eat or drink. We can ignore the food, but we must water them on time as usual to keep the humidity of the nests suitable and control the temperature between 20℃ and 36℃. If the temperature and humidity are not appropriate, too high or too low, the incubation will be interrupted, the embryo will stop developing and die. If the incubation conditions are suitable, after about 40 days of incubation, the 3 cm long light blue centipedes will begin to leave the nests and come out to move around and look for food.

It is difficult to distinguish immature centipedes from their appearance. They only become slightly different when they mature, and can only be distinguished by careful comparison after maturity. The general differences are: First, the female centipede has a flat and round head, which is larger and pancake-shaped; the male centipede has a slightly raised head, which is oval and small, and spore-shaped. Second, the rear edge of the 21-segment dorsal plate of the male centipede is relatively flat and round, while the rear edge of the male centipede is slightly raised. Third, the male centipede is larger in size, with a wider trunk, a thick abdomen, and a softer body; while the male centipede is smaller in size, with a slightly narrower trunk, and a tighter and thinner abdomen. In addition, in artificial breeding farms, female centipedes are less active and slow, while male centipedes are active and agile.

2. Centipede laying eggs

It is not suitable. Because before the centipedes lay eggs, they are forcibly isolated in the pond with glass or cans. Although this avoids interference from other centipedes, the isolated centipedes also lose their freedom of movement and cannot find a suitable place to lay eggs. They can only be trapped in an artificial protective cover, which is not necessarily the place where centipedes need to lay eggs. The above information comes from Zhang Chongzhou's centipede breeding technology. If you want more details, go to Baidu to search

3. Through the dead centipede, I found golden eggs in the centipede's body, but I don't know how long it will take for it to lay eggs~!

Centipedes can only reproduce once a year. Some farms say centipedes can reproduce several times a year, but this is all false. Centipedes reproduce around the beginning of summer. They can reproduce about 50 at a time. This is the physiological habit of centipedes.

4. Are centipedes oviparous?

Centipedes are dioecious and are oviparous.

The gonads of the centipede's reproductive system are all on the back of the digestive tract. They are single ovaries or testes, and have a reproductive tube, the oviduct or vas deferens, which later splits into two, goes around the digestive tract and opens at the male and female genital openings. In addition, there are two pairs of accessory glands connected to the end of the reproductive tube. The female centipede has two spermatophores, and the male centipede has two spermatophores, which all lead to the ends of the oviduct and vas deferens.

The eggs of the female centipede fill the body cavity when mature. Before giving birth, the mother stores sperm in the spermatheca so that the fully developed eggs can combine with the sperm during ovulation, become fertilized eggs and be discharged from the body.

5. How many times a year does a centipede lay eggs?

Centipede reproduction times: generally once, a few twice. More than twice is unrealistic. Do not believe the reproduction times advertised by seed speculation companies: 2-5 times per year
