How Do Spiders Create Horizontal Webs?
Spiders build webs in a variety of ways. Some build a sheet web, which is a vertical or horizontal sheet of threads that encloses a large area. The web is used to trap prey. In addition, it provides a safe retreat for eggs and larvae.
Spiders use vibrations of the web strands to locate their prey. They may wrap larger prey in threads to immobilize them. Once entangled, the spider shoots venom into the prey’s gut. This turns the gut liquid.
Orb-weaving spiders have six spinnerets. These are the organs in the spider that generate silk. Each of the spinnerets produces a different type of silk thread.
The orb-weaver spider makes sticky silk by applying a glue-like substance to its catching spiral. The threads in the web are then coated with a viscid silk.
While constructing the web, the spiders follow patterns shared by most spider species. These patterns help the web to be geometrically regular. Depending on the particular species, the web can be one-dimensional or three-dimensional.
The first thread of the web is made of strong horizontal silk. This thread will serve as the main support for the web.
Once the main thread is attached, the spider will reinforce the strand. It will also recycle the proteins that are consumed in making the web.
When the web is finished, the spider will move toward the center. A temporary spiral will be laid down to provide scaffolding for the permanent sticky spiral.
