How do centipedes reproduce?
The centipede grew for 3 ~ 4 years, matured as long as 10 cm, and began to reproduce. Generally, in late spring and early summer from March to June every year, the temperature rises to more than 25 ℃ and enters the breeding period.
The centipede grows for 3 years (that is, after 3 years of age) and its gonads are mature and can mate and reproduce. The mating period is from May to September every year, mostly at night, but also in the early morning and evening. When mating, the male borer pede climbs to the back of one side of the female centipede, and all the feet are raised. At this time, the female is very tilted, and the other foot is also tilted. When little, the male excretes a whip-shaped seminal vesicle from the reproductive foramen, which is sent to the female, and mating is completed.
At the end of spring and the beginning of summer, the eggs in the ovary gradually develop and mature. Generally, the number of eggs laid is 20-60, mostly 40-50, and a few less than 10. The spawning season is from late June to early August, that is, from the Summer Solstice to the Beginning of Autumn, and the spawning period is in the early and middle of July.
Centipedes need to molt several times from egg hatching, larval development, growth to adult, and grow up obviously every time they molt. Adult centipedes usually shed their skin once a year and a few twice a year. Before molting, the adult centipede has wings on its back without luster, its body color changes from black and green to light green with slightly scorched yellow, its feet change from red to yellow, its whole body is muddy and thick, it is slow to move, it does not enter food, and its eyesight and tactile ability decreases, so it can not escape quickly after poking.
