is a device created by a spider out of proteinaceous spider silk extruded from its spinnerets, generally meant to catch its prey.

Spider webs have existed for at least 100 million years, as witnessed in a rare find of Early Cretaceous amber from Sussex, southern England. While this large family is also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, they actually have a huge range of web architectures.

It is hypothesized that these types of aerial webs co-evolved with the evolution of winged insects.

As insects are spiders' main prey, it is likely that they would impose strong selectional forces on the foraging behavior of spiders.

Most commonly found in the sheet-web spider families, some webs will have loose, irregular tangles of silk above them.

After the spider has completed its web, it chews off the initial three center spiral threads then sits and waits.

If the web is broken without any structural damage during the construction, the spider does not make any initial attempts to rectify the problem.
