COBWEB
Cobwebs are a sticky mess. Unlike other webs, the design of cobwebs is irregular. The webs are jumbled which explains why they are sometimes called tangled webs.
If you spot a web in your house, there’s a good chance it’s a cobweb. Spiders weave these webs in corners and near ceilings, making sure that the web is anchored to something.
The Theridiidae family has mastered the art of cobweb creation. These spiders, including the black widow, rely on the sticky web for catching their next meal.
