Male spiders have many complex courtship rituals and have to avoid being eaten by the females, with the males of most species survive a few matings, and having short life spans. Pre-copulatory mate choice processes have been observed in a wide range of spider species, including Stegodyphus lineatus, Argiope aurantia, Schizocosa floridana, Hygrolycosa rubrofasciata, and Schizocosa stridulans. Sexual selection occurs after copulation as well as before copulation. Post-copulatory sexual selection involves sperm competition and cryptic female choice. Sperm competition occurs when the sperm of more than one male competes to fertilize the egg of the female. Cryptic female choice involves the expelling of a males sperm during or after copulations.a males sperm during or after copulations.
