Much of the orb-spinning spiders' success in capturing insects depends on the web not being visible to the prey, with the stickiness of the web increasing the visibility, thus decreasing the chances of capturing prey. If the prey is a venomous insect, such as a wasp, wrapping may precede biting and/or stinging. Characteristically, the prey insect that blunders into the sticky lines is stunned by a quick bite, and then wrapped in silk. The third claw is used to walk on the nonsticky part of the web. The rest of the scaffolding follows with many radii of nonsticky silk being constructed before a final spiral of sticky capture silk. The spider secures the line and then drops another line from the center, making a "Y". The building of a web is an engineering feat, begun when the spider floats a line on the wind to another surface. Generally, orb-weaving spiders are three-clawed builders of flat webs with sticky spiral capture silk. Their webs are strikingly similar, but use a different kind of silk. The cribellate or hackled orb-weavers ( Uloboridae) belong to a different group of spiders. The family Arkyidae has been split off from the Araneidae. The long-jawed orb weavers ( Tetragnathidae) were formerly included in the Araneidae they are closely related, being part of the superfamily Araneoidea. Orb webs are also produced by members of other spider families. Araneid webs are constructed in a stereotypical fashion, where a framework of nonsticky silk is built up before the spider adds a final spiral of silk covered in sticky droplets. With 3,067 species in 177 genera worldwide, the Araneidae comprise the third-largest family of spiders (behind the Salticidae and Linyphiidae). The family has a cosmopolitan distribution, including many well-known large or brightly colored garden spiders. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs. The English word "orb" can mean "circular", hence the English name of the group. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. Orb-weaver spiders are members of the spider family Araneidae.
