In some cases, spiders may use silk as a food source. [1] While methods have been developed to collect silk from a spider by force, [2] gathering silk from many spiders is more difficult than from silk-spinning organisms such as silkworms. All spiders produce silk, although some spiders do not make webs. Silk is tied to courtship and mating.
Spiders make spider silk for various purposes such as weaving their webs, protecting their eggs or as a safety line. The amphipod Peramphithoe femorata uses silk to make a nest out of kelp blades. Another amphipod, Crassicorophium bonellii, use silk to build shelter. Carp produce fibroin units, a component of silk, to attach their eggs to rocks ...

The term "spider web" is typically used to refer to a web that is apparently still in use (i.e., clean), whereas "cobweb" refers to a seemingly abandoned (i.e., dusty) web. [3]
Crumbley explains that control of spiders comes in two forms: knocking down webs and removing their food sources: Webs can be knocked down with brooms or long dusting wands. Knocking down webs ...

The cribellate spiders were the first spiders to build specialized prey-catching webs, later evolving into groups that used the spinnerets solely to make webs, instead using silk threads dotted with droplets of a sticky liquid (like pearls on a necklace) to capture small arthropods, and a few large species even small bats and birds.
