text: Males of sexually cannibalistic species use diverse strategies to decrease their chances of being cannibalized: male scorpions sometimes sting the female after deposition of the spermatophore (Polis and Farley 1979); male black widows (Gould 1984) and crab spiders (Bristowe 1958) often restrain females in silk prior to copulation; certain tetragnathid spiders have specialized jaws that hold open the jaws of females during copulation (Bristowe 1958); many orb-weavers preferentially mate with females in ecdydis, when cannibalism is physically impossible (Robinson 1982); other orb-weavers (Robinson 1982) and a jumping spider (Suttle, personal observation) delay their courtship approach until a female catches another prey item.
