Why do spiders sometimes eat their own webs?
Quick Answer
Spiders recycle silk protein by consuming old webs. This helps them recover valuable nutrients and build a fresh trap.
The Full Story
Web silk is made of proteins, so spiders can reclaim part of the material by eating a web they no longer need. This is especially common in orb-weavers that rebuild regularly. Recycling silk saves energy and nutrients that would otherwise be lost. After digestion, the spider can spin new silk tailored to current conditions. This is an efficient strategy in an animal that depends on silk as both tool and food investment.
