1. Orb webs: These are symmetrical, circular webs with radial spokes and sticky spiral threads. Orb webs are commonly built by orb-weaver spiders (Araneidae family). The spiders hang upside down in the center of the web, waiting for prey to get trapped in the sticky threads.
2. Sheet webs: Sheet webs are flat, horizontal webs with a tangled network of threads. They are constructed by sheet-web spiders (Linyphiidae family). These spiders typically sit on the surface of the web, hidden among the threads, and wait for prey to walk over them.
3. Funnel webs: Funnel webs are tube-shaped shelters made of silk. They are built by funnel-web spiders (Agelenidae family). One end of the funnel leads to a burrow or crevice where the spider hides. The other end is open, and the spider waits inside the funnel for prey to enter.
4. Tube webs: Tube webs are cylindrical structures made of silk. They are constructed by tube-web spiders (Segestriidae family). The spider lives inside the tube and waits for prey to come close before capturing it.
5. Retreats: Some spiders construct silken retreats or shelters under leaves, rocks, or other objects. These retreats provide protection and serve as resting places for the spiders.
Spiders use these shelters for various purposes, such as capturing prey, protection from predators, and finding suitable microclimates for survival.
