This includes various types of webs, all of which have an open, spatial and somewhat disorderly appearance.
The cob web of Cob web spiders (Theridiidae) consists of tangled, messy silk together with threads that are tightly stretched against the surface. These threads have small adhesive droplets. If a crawling insect gets stuck, the thread detaches and the prey is lifted off the ground. Another example is the cribellate web that also consists of messy threads and is spun by Hackled mesh weavers (Amaurobiidae). These webs can often be found against walls and do not contain any adhesive. However, the spider combs the silk with the hind legs making it very curly. This ensures that the web works like velcro and is a very efficient way to trap insects. The Cellar spider, which you often see in the corners of the garage, garden shed or bathroom, also makes a messy web.
