Why don’t Spiders Stick to their Webs?
How does a Spider Web look like?
A spider’s web is built similar to a bicycle wheel, with an outer rim and spokes running towards the centre, and a spiral from the centre back out to the rim. The spokes and outer rim are made from dry silk while the spiral is the only bit that is coated with glue.
How do Spiders not stick to their webs?
The spider is smart enough to avoid the sticky sections as it moves and it has very minimal contact with the web, in any case.
Spiders also constantly groom their legs to keep them clear of silk and glue. Spiders do not have oil-producing glands, nor are their legs coated in any such substance. A common misconception about spiders is that some kind of natural lubricant or oil on their legs prevents silk from adhering to them. This is entirely false.
