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.
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.
This spider is a common but often uncomfortable sight and has been dominating populations around the Palmetto State.
