The spider makes a tube of silk in the ground and with a roof of cribellate silk on the ground. The female and the not adult male are colored black and velvet. The male spider only gets its coloring at his last change of skin. Then he leaves its home and starts wandering looking for a female. The male becomes adult in the autumn or in spring.
Females can become four years old and never leave their hiding.
They make one cocoon with eggs. At daytime they bring out their cocoon and let it warm in the sun. At night the cocoon is return in the hiding. The young spiders stay in the housing tube during the winter and stay with their mother for quite a long time. During this time they may change skin for six times.
