Double-tailed web spiders mate during summer. After mating, the female will lay her eggs in an egg sac (an ovoid ball of spider silk) in her sanctuary. She then stretches her body over the surface of the egg sac and guards it. This behavior is distinctive and makes the species easy to recognise. [9]
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.
The two spiders mate and cohabit until the male dies, when the female eats him. The female makes an egg sac and hangs it in her burrow. The next summer, the eggs hatch, and the spring after that, the spiderlings leave their mother's burrow and wander off to find a suitable place to build a lair of their own.
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.

Bolas: Bolas spiders are unusual orb-weaver spiders that do not spin the webs. Instead, they hunt by using a sticky 'capture blob' of silk on the end of a line, known as a ' bolas '. 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.
