How many months have wild scorpions been there?
Scorpions have the habit of hibernating. Generally, they go out in the middle and late April, that is, after being frightened.165438+1early October began to hibernate slowly. The annual activity time is about 6 months. During the day, scorpions usually come out from 8 pm to 1 1 after sunset and return to their nests at 2 ~ 3 am the next day. This activity pattern is generally in warm, windless and dry nights, and rarely occurs in windy weather. Scorpions are still relatively cold-resistant and heat-resistant. The temperature of the external environment is 40℃ to MINUS 5℃, and scorpions can survive. The growth, development and reproduction of scorpions are closely related to temperature.
Female scorpions can give birth to young scorpions from reproductive holes, and male scorpions can produce sperm from reproductive holes intersecting with female scorpions. There are only two sperm rods in the male scorpion, and they can only mate twice in their life. Female scorpions mate 1 time, and can give birth continuously for 4 years until the end of their lives. Scorpions live for 5-8 years. Scorpions are viviparous, and fertilized eggs complete embryonic development in the mother. The temperature is between 30 ~ 38℃ for delivery.
The embryo is at the end of the cecum, and another tube extends here. At its end is a cluster of absorptive cells, which are close to the blind sac of the digestive system. The absorbed nutrients are transmitted to the embryo along the tube, which is a bit like the umbilical cord of mammals. The development has gone through several months or even 1 year. There are 6 ~ 90 young scorpions, which vary from species to species. After giving birth, the young scorpions immediately climbed onto the back of the mother scorpion, skinned it once, and left the mother scorpion one by one to live independently. Buthus martensii gives birth in July and August.
Before giving birth, the female scorpion looks for a suitable place, and the two comb-like organs spread to the left and right, and are produced one after another from the reproductive hole. Young scorpions are covered with white mucus and are rice-shaped. After a few minutes, the tail and appendages of the young scorpion spread out from the mucus and climbed up the back of the mother scorpion with the appendages of the mother scorpion. Give birth to 15 ~ 35 young scorpions per fetus. The newborn scorpion is about 1 cm long, milky white, with only black eye mound; The teeth, protrusions and claws on the body and appendages have not yet grown out; Don't eat any food on mom's back. Five days later, it peeled off and became a 2-year-old scorpion, which was more than 1.5 cm long and still lived on its mother's back. After about 1 week, she left the mother camp and lived independently. * * * After 5 skinning (6-year-old scorpion), it will become a scorpion in the third year, but it will not reproduce until the autumn of the fourth year. From birth to reproduction, it takes about 3 years, and it can reproduce continuously for about 5 years, with a life span of 8 years.
