[20][21][4], Araneid species either mate at the central hub of the web, where the male slowly traverses the web, trying not to get eaten, and when reaching the hub, mounts the female; or the male constructs a mating thread inside or outside the web to attract the female via vibratory courtship, and if successful, mating occurs on the thread.

Female southern house spiders measure from 12 to 18 millimeters long, and males measure 8 to 12 millimeters long. [19] While early molecular analysis provided more support for a monophyletic origin,[10][13][14] other evidence indicates that orb-weavers evolved earlier phylogenetically than previously thought, and were extinct at least three times during the Cretaceous. Common spiders in the state include the brown recluse spider, black widow, and tarantula. Orb webs are also produced by members of other spider families.

This type of fly is known to gravitate toward artificial light sources at night. Special Orb Weaver Adaptations and Defenses . [6] Though it could be expected for these spiders to just know these things, it isn't well researched yet as to just how the arachnid knows how to change their web design based on their surroundings. They are part of the orb weaver family and spend their time in large, orb-shaped webs that can stretch up to several feet wide. [25] The larger size female is typically thought to be selected through fecundity selection,[26] the idea that bigger females can produce more eggs, thus more offspring. [15] Vollrath and Selden (2007) make the bold proposition that insect evolution was driven less by flowering plants than by spider predation particularly through orb webs as a major selective force.

Spitting spiders are not aggressive towards humans unless provoked; however, the venom can be dangerous if injected directly into human tissue. [22] Here larger males may be less likely to be cannibalized, as the males are able to copulate while the female is hanging, which may make them safer from cannibalism. Although a great deal of evidence points towards the greatest selection pressure on larger female size, some evidence indicates that selection can favor small male size, as well. This species of spider comes in many colors.
