 | Spiders reproduce by eggs laid in silk bundles called egg sacs, and the male (usually significantly smaller than the female down to 1% for Tidarren sisyphoides) is likely to be killed by the female after the coupling, or sometimes before intercourse has occurred. |
| When sexually mature, a male spider will spin a web pad onto which the contents of the abdominal reproductive organs are discharged and then the seminal fluid is transferred into the cavities of the palpi; when an individual secures a mate he thrusts the palpi one at a time into her abdominal genital openings. |
| The widow spiders, brown recluse spiders, hobo spiders, and yellow sac spiders are the dangerous ones among U.S. spiders. |
