This seasonality of reproduction is largely due to the male spiders, who spend the winter months molting to adulthood, while female spiders are present year-round. This is evidenced by the reduction in eggs found during winter months. Egg clutches are enclosed in a 5 mm thick cocoon, hidden about 12 cm deep in the burrow.
A male Eresus sandaliatus. Sexual selection in spiders shows how sexual selection explains the evolution of phenotypic traits in spiders.Male spiders have many complex courtship rituals and have to avoid being eaten by the females, with the males of most species surviving only a few matings and consequently having short life-spans.
Only near the end of the female's second year of life will she allow males onto her territory to mate. Females lay their eggs most commonly in the middle of the summer; these hatch after 3.5 weeks. [3] Females usually die very soon after their eggs have hatched, during their second winter. [20]

By swinging the bolas at flying male moths or moth flies nearby, the spider may snag its prey rather like a fisherman snagging a fish on a hook.
Nursery web spiders are known to be univoltine, [7] which means it only has one brood of offspring per year. The care of the offspring is typically solely the female's responsibility; from carrying eggs to maintaining the sac until hatching, the female does most of the work, and the male's role is very limited.
Trichonephila clavata pass winter as eggs and scatter as tiny juveniles in the spring. Like most spiders, females are much larger than males. The adult female's body size is 17–25 millimetres (0.67–0.98 in) while the male's is 7–10 millimetres (0.28–0.39 in). The web of females may reach several meters in length.
