Why is the garden spider's web stiky?
It is sticky because the silk is put out by the spider with an adhesive on it. The adhesive functions to fasten prey to the web. The spider then comes out and tries to wrap the prey in non-sticky web. If it didn't do that then the insect might finally pull lose. If the spider can get an insect caught in the "glue" on its web and then wrap some extra silk around it to keep it from moving freely, then the spider can give it a venomous bite. Soon the prey will stop struggling and the spider can settle down to dinner.
