Will spiders abandon their web if not enough food is caught in it?

Not usually. They will usually just die in the web if they dont get enough food. 

Its all natural selection. Thats why spiders have hundreds of spiders in each egg. When they are born, they let out a strand of web into the breeze, and they are small enough to be picked up by that wind and blown almost anywhere. Its called balloning. Where it lands, it makes its web close to that and there it will stay, till death, or it dies of old age. 

This is for web spinning spiders and not hunting spiders, which obviously hunt down their food and dont make a web to live in.
