More advanced webs, particularly of orb-weaver spiders, are highly intricate, raised above the ground, and oriented to intercept the paths of flying insects. The spinning itself is a complex process involving the placement and then removal of scaffolding spirals and a combination of sticky and nonsticky strands. In some cases a number of spiders will form a kind of communal web, but spiders in general are not social. Such spiders rely largely on the sense of touch. Hunting Spiders Besides the web spinners, many spiders hunt for their food or lie in wait for it.
Hunters tend to rely on vision if they feed during the daytime, or on touch if they feed at night.
Jumping spiders may lurk in ambush for their prey, and a number of them are well camouflaged on flowers by color or body structure or both. Reproduction Spiders have separate sexes, and the eggs have to be fertilized. The genital openings of both male and female are located on the abdomen. The male's copulatory organs, however, are complicated structures located on his pedipalps. He spins a little web and deposits sperm in it, then moves the sperm to the palpal organ.
