A spider web, spiderweb, spider's web, or cobweb (from the archaic word coppe, meaning "spider") [1] is a structure created by a spider out of proteinaceous spider silk extruded from its spinnerets, generally meant to catch its prey.
Spiders make their webs from silk, a natural fibre made of protein. Not only does spider silk combine the useful properties of high tensile strength and extensibility, it can be beautiful in its own right.

Some webs are extremely intricate. Most people assume that the design is purely functional, but this is not always the case. Some spiders, particularly the large family known as orb weavers, actively decorate their webswith extra silk designs known stabilimenta. The name “stabilimenta” represents the bias of early researchers who assumed that these...
The presence of deliberate structure dispels another common misperception about spiders, that they set up in a promising area of insect travel and wait to see what happens. However, many spiders seem to be far more proactive in their web building, building webs that are designed to actively attract insect prey, not just trap the unlucky.
Many insects have better visual perception in UV wavelengths of light. Spiderwebs are much more reflective in UV light, possibly attracting insects. The decorations may also resemble vegetation gaps where insects are more prone to fly.
Decorations come with a risk; while they might attract more insects, they are also more visible to predators who may threaten the spiders. When you see a web with old exoskeletons and egg sacs hanging in it, it could well be the case that the spider left those on purpose as camouflage.
Overall, web size is also carefully set. Most insects caught by spiders are small; a larger web increases the odds of catching more flies. However, spiders may not be able to fully thrive and reproduce while consuming solely run-of-the-mill small insects. In a study of orb weavers, most spiders rarely caught more than 2 small insects per day. For t...
Many spiders actually replace their entire web every single day. Larger webs cost the spider more energy to produce, which really adds up with each rebuild. Large catches apparently more than offset the increased energy output. So really, spider webs are more amazing even than they first appear. For a construction job done right, get a spider to do...
