The males leave their burrows in search of a mate. The courtship period takes place over several hours. The males are dancing. At the same time, they form a protein liquid, which leads the female to a catalyptic state. Pedipalps carry seminal fluid into the genital opening.
If there are several males, a duel begins. 2 months after fertilization, males live in burrows with females. The female is engaged in the manufacture of a cocoon. There can be about 80 eggs in a cocoon.
The female weaves the skin of insects, grass, leaves into a cocoon to disguise it. During the day, she warms him under the bright rays of the sun, and at night she takes him to shelter. The life expectancy of a female is 1,5 years, and a male is 8 months.
