Question: What is the optimum life of a spider’s web? What happens to the web
after this period?
Answer: The optimum life of the characteristic orb webs is usually one day.
Every night the spider ingests her old web (generally only the females spin
webs), gaining additional energy from nutrients such as pollen that stick to it.
She then spins a new web either in the same place, or in a different one,
depending on how good she considers the site to be.
