Reproduction and species of insect

Breeding
Fertilization dvuvostok usually occurs in late summer.
Fertilized females hibernate in the soil in previously prepared nests. Eggs usually occur in the spring, but sometimes in the fall, in which case the female winters in the nest together with laid eggs.
The male is also in the same nest with the female, but rarely survives until the onset of spring.
Having laid the eggs, (one clutch contains from 40 to 100 eggs), the female is constantly near the future offspring, protecting the eggs from the encroachments of uninvited guests for the entire period of their maturation until the appearance of larvae.
Larvae from adults differ in the size of the body and the absence of wings. A gradual transformation takes place as a molder, until the earwig turns into an adult insect.
