Why is a spider spinning?
Spiders spin webs to protect their eggs or as a hunting tool, a small silk net that they throw over their prey. They can also use webs for transport, climbing to a high point and then release one or more sail-like strands of silk which get caught by the breeze and carries them away.
Why do spiders hang?
While there are exceptions, this position gives spiders an advantage when getting food. Sometimes prey will hit the top of the web, but end up tumbling to the bottom of the web. A spider higher up on the web with its head facing down would be able to see prey below. Gravity also helps spiders as they run down the web.
Why do spiders vibrate the web?
They weave their webs to catch prey and attract mates. But while humans can generally spot an insect trapped in a web, spiders—which have extremely poor eyesight—can’t. Instead, they appear to rely on vibrations from the silk strands to locate prey and find deformities in the web.

How do spiders listen?
Over the years, studies have proven that spiders sort of hear with the teeny hairs on their crawly legs because the fuzz is sensitive toward nearby sound vibrations, but that’s pretty much as far as experts thought arachnid auditory senses go — until now, that is.
Why do spiders bounce?
Some spiders shake their webs to remove debris or learn something about the prey caught in the web. But in this case it’s most likely that the spider sees something that it considers a threat, and it is bouncing to confuse and encourage the threat to move along.
