 Like many species of spider , a P. schultzi lays a continuous dragline of silk as it moves , and from time to time anchors the dragline to a surface with a spot of sticky silk . This allows the spider to return to the surface if the animal is dislodged . A spider about to jump first lays a sticky silk anchor , and then lays out a dragline as it flies . : 574 Unlike those of most jumping spiders , P. schultzi ′ s draglines stick to each other and , when a P. schultzi has laid a few lines across a gap , it uses these as walkways and reinforces them with additional silk as it moves . : 34
