Cobweb spiders spin an irregular web that can be described as an intersecting mass of scaffold work with a central area consisting of a three-dimensional trellis of silk. The common name "comb-footed spider" results from the  "comb" on their last pair of legs. The comb is a series of serrated spines which they use to comb out the silk from the spinnerets. This combed silk is not sticky but insects get entangled in it. The black widow spider is a member of this family. [2]
